Description
MODULAR PRINTER SYSTEM
DESCRIPTION 13 3 8 0 ~ 9 This invention is particularly concerned with printer devices such as are utilized in connection with product delivery e.g. to retail stores. In a field known as route accounting, a computerized terminal maintains price and quantity information concerning various items to be delivered at a series of stores, and a printer unit is utilized to produce a printed record for each customer. The printer may be carried into each store with the terminal, or the printer may be part of the fixed equipment within a delivery vehicle.
In a typical route accounting system, a portable modular printer device may comprise a briefcase containing the printer unit. Preferably such portable systems have a receptacle for plug-in coupling of a computerized terminal.
In the past, systems providing an eighty column printing capacity have utilized portable configurations representing relatively high cost beyond the cost of the basic printer unit, and adding very substantially to the basic weight of the printer.
It is conceived that it would be highly beneficial to create a portable printer system requiring only minimal additions in terms of cost and weight over that of the basic printer. It would be ideal if a modular standardized construction could be applicable also to non-portable printer systems and capable of readily receiving computerized terminals of different configuration.
Accordingly, it is a basic objective of the invention to provide a portable printer device which adds only minimal cost and weight to a basic printer unit.
A further object is to provide a modular printer device which is of particularly compact and convenient dimensions for portable use and yet which is readily 1~ ~ 8 ~ 49 73164-25 converted to use in non-portable applications such as are common in the route accounting field.
Another related object is to provide a basic standardized frame construction which is readily adapted to the reception of improved printer units and more compact computerized terminal configurations as such become economically feasible.
A particularly advantageous embodiment of the invention utilizes a standardized open frame construction for receiving a modular printer assembly and a modular terminal assembly. The frame may have an external configuration so as to snugly receive a carrying handle and/or other attachment suitable for a portable device, or to receive an auxiliary terminal mounting bracket facilitating use as a non-portable installation. A paper tray module for the printer unit may itself provide the bottom closure for the standard open frame, and serve with the frame as part of a water repellant encasement for the modular printer assembly. The printer housing module may accommodate one hundred and eighty degree reversal of the printer unit to adapt to portable or vehicle mounting. A low cost printer adapter means may adapt a printer housing module to different printer units, and a light weight economical terminal module may serve to adapt the standard frame to different size terminal configurations of a terminal family.
According to a broad aspect of the invention, there is provided in a modular printer system, a modular printer device for containing a computerized terminal for supplying data to be printed and a printer means for printing data supplied by a ,~

DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS
In FIG. 1, a unitary modular portable printer device 10 is shown as comprising a standardized open l33sa43 frame module 11 having a paper tray module 12 assembled therewith as bottom closure.
Eitting within the open frame 11 are a terminal module 14 with a hinged cover 15, and a printer module 16 having a paper outlet slot 16A which may be selectively covered by means of a laterally shiftable cover strip 17.
A carrying handle 18 is slidably engaged with an external side of the open frame 11.
As seen in FIG. 2, the open frame 11 is composed of four rectilinearly arranged frame elements 21-24 and a single additional frame element or crosspiece 25 subdividing the open frame to provide a terminal receptacle 26 and a printer receptacle 27.
As shown in FIG. 2, the terminal module 14 has downward directed horizontal surfaces such as 14A and 14B
at the four side thereof which are upwardly offset relative to a bottom 14C of the terminal module.
Vertically disposed side walls such as 14D and 14E extend from the outer perimeter of the bottom 14C to inner margins of the surfaces such as 14A and 14B. The terminal module 14 fits into receptacle 26 with surfaces such as 14A and 14B resting on four rectilinearly arranged ledge portions such as 23A and 24A which are provided by the frame elements 21, 23, 24 and 25. These ledge portions at their inner edges confront the terminal module side walls such as 14D and 14E when the terminal module is assembled therewith.
Thus the ledge portions such as 23A, 24A of the frame elements 21, 23, 24 and 25 may be taken as principally defining terminal module receptacle 26.
Similarly ledges such as 23A and 25A of frame elements 21, 22, 23 and 25 support upwardly offset surfaces such as 16A and 16B of printer module 16, and confront side walls such as 16C and 16D, and may be taken as essentially defining printer module receptacle 27.
_ 1338043 -6-The terminal module 14 releasably receives the computerized terminal 30 upon opening of cover 15. sy way of example the terminal module 14 may have an interior space of size to receive terminals known as the model 121XL and model 141XL of the Norand Corporation, Cedar Rapids, Iowa.
Such terminals 30 have a display region 31, a keyboard region 32 and a battery compartment region 33, and may be used for route accounting operations, for example. The terminal 30 may have an electrical interface at its end 35 which may comprise a 15-pin connector which mates with a mating connector within module 14 as the terminal is inserted into its module. A
terminal 30 may weigh about one kilogram including batteries, memory and communications adapter. As with present printers of Norand Corporation, the electrical interface at 35 and other constituents of terminal 30 may allow the supply of data to the terminal module interface for printing by means of the printer unit within printer module 16.
By way of example printer module 16 may be of interior configuration to receive a commercially avail-able eighty column printer which can print on three-ply fanfold paper supplied by the paper tray module 12, e.g.
paper having a width between 5.0 inches and 10.0 inches.
An example of such a printer is the Citizen MPS-20.
Paper tray module 12 may for example, for the portable device have a capacity of fifty sheets of three-ply paper. As an option for a non-portable ~evice as in FIG. 3, a paper tray module may have a capacity of two hundred three-ply sheets.
FIG. 2 shows the frame element 21 as including upper and lower flange portions 21A and 21B which have opposed edges overhanging a central body portion 21C so as to define a guideway 37 for receiving a slider member 38, FIG. 5, integral with the carrying handle 18. A
slmllar guldeway 39 ls deflned by flange portlons of the frame element 23.
In FIG. 3, the open frame 11 and paper tray 12 may be ldentlcal and yet provlde a non-portable subassembly 40 whlch may dlffer from portable devlce 10 by the absence of handle 18, and attachment of a slde arm bracket 41 to the frame 11. The bracket 41 may form a termlnal cradle wlth a termlnal module receptacle 42 recelvlng a termlnal module 14 ldentlcal to that recelved by portable devlce 10. The prlnter module receptacle 27 ls ldentlcal to that of the portable devlce 10, so as to recelve the prlnter module 16 ln the same orlentatlon as ln FIG.
1, or reversed as in FIG. 2. A second termlnal may be located at 42, FIG. 3, where lt may be automatlcally malntalned ln a charged condltlon by means of a charger connected wlth vehlcle power. A lockable llft-up cover of module 14 may retaln a termlnal 30 slmllarly to the way shown ln a brochure number 960-382-509 of Norand Corporatlon whlch has a 1985 copyrlght notlce and whlch relates to a data system for bakery dlstrlbutlon. The brochure provldes background lnformatlon as to exemplary functloning of the computerlzed termlnal 30 and of the lllustrated prlnter systems.
FIG. 4 shows a non-portable prlnter subassembly 40' ldentlcal to subassembly 40 except that the slde arm bracket 41 ls mounted on the left slde of the prlnter module receptacle 27 lnstead of the rlght slde as ln FIG. 3. In FIG. 4, the termlnal module receptacle 26 ls shown ready to recelve a second termlnal module so that two.termlnals such as 30 may be present where deslred. For example, one termlnal at 26 may be recharged whlle the second terminal 30 is removed from a terminal module 14 secured in receptacle 42 for use durlng dellvery to a retall store or the llke.
As best seen ln FIG. 4, the slde arm bracket 41 may have a sllder member 41A lntegral therewlth whlch is slldably engageable ln guldeway 37, FIG. 3, or guldeway 39, FIG. 4.
Sultable means, not shown, may retaln the handle or termlnal cradle ln assembled relatlonshlp to the frame, e.g. screws or the llke. Slmllarly, the termlnal and prlnter modules may be flxedly retalned with the open frame e.g. by threaded fasteners.
By way of example, the portable printer devlce 10 of FIG. 1 may conslst essentlally of open frame 11 wlth handle 18, tray module 12 secured to the open frame 11, termlnal module 14 secured to the open frame 11, and prlnter module 16 secured to the open frame 11 and contalnlng a prlnter unlt whlch can be readlly removable from module 16 to provlde qulck access to the paper tray 12. The termlnal module 14 may removably recelve a computerlzed termlnal such as 30, FIG. 2, essentlally as shown in the abovementloned brochure number 960-382-509 of 1985 for the case of a van-mounted prlnter lnstallatlon or for the case of a multl-termlnal charger lnstallatlon (except that a manually operated latch may be substltuted for a lock on the hlnged cover 15)-The termlnal module for a glven termlnal conflguratlon ls essentlally the same for portable and non-portable devlces.
, .
The termlnal module ls fleld replaceable by the customer through the use of slmple tools so that the customer has the optlon of replaclng an orlglnal termlnal module wlth one for a new termlnal, e.g. a physlcally smaller termlnal.
By way of example, a non-portable prlnter devlce may conslst essentlally of a subassembly 40 or 40' formed of the open frame 11 and paper tray 12, together wlth a slde arm termlnal cradle 41 and a prlnter module 16 secured to the frame 10. Module 16 would agaln contaln a prlnter unlt whlch ls readlly removable so as to provide qulck access to the paper tray module for the replenlshlng of the paper supply.
In the portable and non-portable devlces, the prlnter and termlnal keyboard are preferably operable wlthout removlng or llftlng a cover. The overall dlmenslons of each devlce, excluslve of parts 18 or 41, may be less than 5 1/2 lnches hlgh, 15 1/2 lnches wlde and 14 1/2 lnches deep. The portable devlce wlth a self-contalned chargeable battery (not shown) for the prlnter unlt may have a welght of less than twelve pounds excludlng termlnal 30. The battery when fully charged may provlde for 10,000 llnes of prlnted output.
A DC/DC battery charger may be an optlonal source of overnlght trlckle charglng for the prlnter battery from a route vehlcle battery, slmllarly to the Model NP207 brlefcase prlnter of Norand Corporatlon.
As ln the systems of brochure 960-382-509 of 1985, the portable and non-portable systems hereln provlde for data communlcatlon from the termlnal 30 vla the termlnal module 14 to the printer unlt assoclated with prlnter module 16. For example, the prlnter unlt may have a pendant cable for receivlng power, data and control slgnals. The length of the prlnter cable may be sufflclent to plug lnto a receptacle of the prlnter module prlor to assembly of the prlnter unlt wlth the prlnter module.
The portable unlt may have an AC/DC battery charger operable from commerclal alternatlng current power for charglng the batterles of a termlnal 30 whlch ls lnserted lnto the termlnal module 14 and for charglng the prlnter battery. By way of example, the battery charger may be located ln extra space wlthln the paper tray 12 along wlth the prlnter battery. An ad~acent electrlc power receptacle may releasably recelve an alternatlng current power cord for supplylng commerclal alternatlng current power to the charger durlng battery charglng operatlon.
Raln covers may be provlded for the portable devlce and may be snapped on over the termlnal module 14 and the 9a ~`
13~8049 -lO-printer module 16. Alternatively strips of synthetic materials which adhere when pressed together, and known under the trademark VELCRO, may be applied to mating edges of the open frame 11 and of a top cover therefor.
To facilitate van mounting of the non-portable device, the printer module 16 may be assembled in re-ceptacle 27 in a first orientation with the front of the printer adjacent frame element 22 as shown in FIG. 2, or in a second reverse orientation with the rear of the printer adjacent frame element 22 as shown in FIG. 3.
The terminal cradle 40 may be secured at either of two opposite sides of open frame 11 as shown in FIGS. 3 and 4.
Data communication between the terminal module 14 and the printer module 16 or preferably the printer unit therein may take place via optical couplers and fiber optic conduits molded into the open frame 11. Optical couplers may be provided at frame elements 25 and 22, FIG. 2, to accommodate a single optical coupler of the printer unit, or the printer unit may be provided with two optical couplers in parallel each registering with a single optical coupling on the frame ll for a respective one of two different orientations of the printer module and printer.
A van mounting plate (not shown) may be provided with tilt adjustment so that the angle of the modular printer device may be optimized in a non-portable installation.
As in the system of brochure number 960-382-509 of 1985, operating power for the charging of the terminal and printer batteries may be obtained from the vehicle power system in which the modular printer device is installed.

Connector 154 is connected with the electric circuitry of the printer device 100 by means of a cable indicated at 160. As previously described, connector 154 and cable 160 provide for data communication between the terminal indicated at 152 and a printer unit associated with printer module 116.
As seen in FIG. 7, terminal module 114 is comprised of a terminal holder base 170 of molded plastic construction (e.g. Cycolac KJW, Borg Warner). The base 170 may be threadedly secured to bosses integral with the underlying frame elements corresponding elements 24 and 25, FIG. 2. The base 170 is provided with a double wall configuration at its opposite longitudinal ends such that the cable 160 may extend within an enclosed chamber 172.
As shown in FIG. 8, paper tray module 112 of the portable device 100 may be provided with a fifty sheet paper bin 180 for holding a supply of paper which is to be automatically fed into the printer mechanism. The paper tray 112-1 shown in FIG. 16 is equipped with a larger paper bin 180-1 capable of holding 200 sheets for automatic feed into a printer mechanism. The larger capacity paper tray module 112-1 is normally associated with a non-portable device such as shown in FIGS. 15 and 16. The paper tray modules 112 and 112-1 may be identical except for the difference in capacity of the paper bins.
As diagrammatically indicated in FIGS. 7, 9 and 10, terminal holder base 170 may have an integral depressed central bottom 190 (FIG. 7) with two integral upstanding _ 13380 49 -13-bosses 191, 192 (FIG. 9) serving to secure the ends of a tension spring indicated diagrammatically at 194. The bracket 150 includes an integral slider piece 200 with an integral depending lug 201 about which a mid region 194A
of spring 194 may extend.
As best seen in FIG. 10, slider piece 200 may have integral depending legs with outturned feet such as 211 which interengage with ledge parts such as 215 which are integral with the terminal holder base 170. The upper edges of the ledge parts such as 215 are chamfered, e.g.
over a distance of .040 inch at forty-five degrees, at their inner edges so that the feet such as 211 will be cammed inwardly as the sliding retainer bracket 150 is pressed downwardly during assembly with the terminal holder base 170. The legs 211 snap into interengagement with ledges such as 215 to hold the parts in assembled relation while accommodating longitudinal sliding motion of the retainer bracket 150.
As seen in FIGS. 7, 9 and 10, the connector 154 has an associated alignment pin 220 which engages in a receiving socket on the terminal 152 and assures reliable interengagement of the connector pins and sockets in spite of manufacturing tolerances. The depressed bottom 190 of the terminal holder base provides a clearance space 221, FIG. 9, into which the slider piece 200 moves to accommodate insertion of one end of the computer terminal 152, FIG. 7, under lip 222 of the retainer bracket 150, and to allow the opposite end of the terminal 152 to be lowered into enqageable ali~nment with the pin 220, after which the bracket 150 is allowed to move to the left (as viewed in FIG. 7) until the terminal 152 is interengaged with connector 154 in readiness for a data transfer operation.
In an embodiment actually constructed, the ledges such as 215 had a length of about 5.4 inches, and the outturned feet such as 211 had a length of about four 1~38049 l4 --inches. The length of the slider piece 200 was about 9.1 inches while its slideway including clearance space 221 was about 10.2 inches, the slider piece 200 being longitudinally shiftable over a distance of about one inch against the action of spring 194.
To fasten the terminal module 114 with the open frame 111, the open frame is provided with four integral tabs such as 231, FIG. 10, having internally threaded sleeves for receiving screws such as 232, FIGS. 9 and 10.
As can be seen in FIGS. 7 and 10, a sealing strip 240 extends about the perimeter of the two openings in the frame 111 with a downturned integral edge 241 of the terminal module 114 being held in sealing relation against the seal strip 240 continuously about the perimeter of the terminal module.
Referring to FIGS. 8 and 10, the paper tray module 180 has bosses such as 250 ( FIG. 8), 251 ( FIG. 10) and 252 ( FIGS. 8 and 10) at respective corners which receiver screws such as 253, FIG. 10, threadedly engaged with the frame 111. In particular, the frame has integral corner tabs such as 254 ( FIG. 8), 255 ( FIGS. 8 and 10) and 256 (FIG. 10) with internally threaded sleeves for receiving the screws such as 253.
As seen in FIG. 9, the paper tray module includes a pair of integral retaining fingers 261, 262 for receiving a battery pack 263 for use during portable operation. A
printed circuit board 264, FIG. 7, occupying a left marginal region of the paper tray 112 may have a plug-in type receptacle thereon adjacent finger 261, FIG. 9, for receiving input direct current operating power from the battery pack.
In the illustrated embodiment the control panel 118 includes an apertured structural member 270A which is an integral part of a one-piece printer case 270 of plastic material (e.g. Cycolac KJW, Borg Warner). The case is of generally open rectangular configuration and overlies four elements of the frame 111 (corresponding to frame elements 21, 22, 23, 25, FIG. 2). The case 270 includes a rectangular perimeter 271, FIG. 10, which continuously sealingly engages the sealing strip 240.
The frame 111 includes an integral crosspiece 280, FIG. 10, with integral tab portions such as 281, FIG. 10, having threaded sleeves to which overlying flanges such as 282 ( FIGS. 9 and 10) and 283 ( FIG. 9) of the printer case 270 are secured by means of screws such as 284.
Corner tabs 254 and 255, FIG. 8, of the frame 111 are threadably engaged with corner flange parts 287 ( FIGS.
8-10) and 288 ( FIG. 8 and 9) as indicated by screw 291, FIGS. 9 and 10.
The printer case 270 is provided with integral inwardly projecting ribs at opposite sides thereof which define printer module mounting means 301, 302, FIGS. 9 and 10. The purpose of mounting means 301, 302 is explained in detail hereafter in reference to FIG. 11.
As seen in FIG.10, each of the mounting means includes a vertical guide channel such as 301A connecting with an arcuate guide channel such as 301B.
As seen in FIG. 8, a rear wall element 270B of the printer case 270 has a series of five notches leaving exposed ledges such as 311 which interengage with hook parts integral with vertical ribs such as 312, FIG. 10.
This provides for a hinged coupling of the rear wall 117B
of cover 117 with the rear wall 270s of the printer case, the frontal edge of cover 117 having a series of cam hooks such as 31~ which can be snapped into engagement with an edge 315 of the printer case 270. When the cover 117 is opened, it ~an be completely removed by pulling the integral hooks of ribs 312 forwardly out of the notches 310.
The rear wall element 270B, FIG. 10, has a sealing strip 320 secured thereon which engages with a lower edge of cover wall 117B when the cover 117 is in closed position. The cover 117 has a further sealing strip 321 which together with sealing strip 320 extends along the entire closure perimeter of the cover 117. A clear soft plastic strip 330 may be secured in a recess 331, FIG. 6, e.g. by means of adhesive at 332, FIG. 10, so that a flap 330A of strip 330 normally covers the paper outlet slot 117A while still allowing paper to be fed therefrom during printing operation.
FIG. 11 shows a printer module 350 interengaged with the printer case 270. In particular the printer module is provided with a generally u-shaped pivot frame 351 of pressed metal which adapts various commercially available printer mechanisms such as 352 to the printer case 270.
The pivot frame 351 has upstanding lateral flanges such as 351A each of which carries a pivot shaft with a disk 355 which fits into a conforming receiving slot such as indicated at 356, FIG. 10, of the printer module mounting means 301, 302, FIG. 9. A limit pin 360, FIG.
11, of each pivot frame lateral flange is of lesser diameter than disk 355 so as to be freely movable in the vertical channel 301A and in the arcuate channel 301B, FIG. 10.
The pivot frame 351 of the printer module 350 is further provided with a pair of longitudinally extending flanges such as 351B which carry rotary latch mechanisms 361. The latch mechanisms each include a sleeve 362 which has an extended position as indicated in dot dash outline at 362-1 and which is shiftable against the action of a compression spring 364 as the printer module pivots clockwise as shown in FIG. 11 from the inactive position 350-1 to the position shown in solid lines at 350. As the sleeve 362 retracts a bar-shaped lug 366 moves through a conforming elongated slot such as 367 in a tab such as 288, FIG. 9. When lug 366 reaches a position below the tab 288, a camming action between sleeve 362 and the lug stem may cause the lug 366 to rotate slightly and interlock with the tab. To release the lug 366, the printer module is rocked slightly in the clockwise direction against the action of spring 364, whereupon the lug 366 is realigned with its slot 367 to allow counterclockwise pivotal movement of the printer module to position 350-l.
The pivot frame 350 further includes a çentral curved extension 351C disposed between the longitudinal flanges 351B and providing a smooth paper guide face 370 which forms part of a paper feed path 371. When the printer module is pivoted to position 350-1, the paper path may be extended as indicated at 371-1.
FIGS. 12-14 show an AC adapter module 400 which is readily applied to the portable version of FIGS. 6-11 in place of foot member 130. For this purpose, the module 400 is provided with internally threaded sleeves at 401-403 so as to be aligned with respective apertures such as that receiving screw 141, FIG. 8. The frame module of FIGS. 13 and 14 may be identical to the frame module 111 of FIGS. 6-11 so that the same reference numeral has been applied in FIGS. 13 and 14, the aperture 410, FIG. 13, being covered by the foot member 130 in FIGS. 6-11.
The adapter module 400 may have a pair of flat raised parts such as 400A, FIG. 13, for resting stably on a flat surface with the handle uppermost. The module 400 has external closure walls 411-416 and butts against frame element 121 so as to provide a first chamber 421 open only at an end 421A, and a second chamber 422 closed at both ends by walls 414 and 416.
A power cord 430 includes a coiled section 430A
stored in chamber 421 and further section 430B extending in chamber 422. An inner end portion 430C of the power cord extends from chamber 422 to a central chamber 433 and then through aperture 410, FIG. 13, in frame 111 and into the interior of the portable device. The AC power 133~Q ~3 -18- .
-may be supplied to a suitable power supply circuit withinthe portable device. Alternatively the power supply circuit may be located within chamber 422, for example.
As shown in FIGS. 12 and 14, a conventional power plug 440 is affixed at the outer end of the power cord and when not in use may be engaged in slots 441 in a closure wall 416A at the adjacent end of chamber 422.
When the power cord 430 is to be connected with commercial AC power, the plug 440 is disengaged from the slots 441 in wall 416A, and the coiled section 430A
withdrawn as far as necessary from chamber 421 through the open end 42lA.
FIGS. 15 and 16 show a non-portable version 500 which may be constructed primarily from the same components as the portable version of FIGS. 6-11. In FIGS. 15 and 16, the frame module 111 may be identical to frame module 111 of FIGS. 6-14 and receive the same reference numerals. In FIGS. 15 and 16, the printer case is identical to the case 270 of FIGS. 6-11 and has the same reference numeral applied thereto. Since the printer case 270, FIG. 16 has been reversed in its receiving space of frame 111, the frame side walls 121 and 123 are to the right and left relative to the control panel 118 which is considered to be at the front of the device.
In FIG. 15, printer cover 117 and paper outlet slot 117A are identical, but are of reversed orientation along with the printer module and printer case 270.
In FIGS. 15 and 16, the receptacle for the terminal module 114 simply receives a cover plate 510, while in place of foot member 130, FIG. 7, the frame module 111 receives a terminal side bracket 520, which secùres to the frame in the same manner as foot member 130, FIG. 8, or AC module 400, FIG. 12. The terminal side bracket 520 receives a terminal module 114 identical to that of FIG.
7. Reference numerals 150, 152 and 222 are applied in 1338~ ~9 -19-FIG. 15 and have been explained in relation to FIGS. 7 and 9.
The aperture 410, FIG. 13, in the frame module 111 is of a size and location to accommodate the cable 160, FIG. 7, for the case of the embodiment of FIGS. 15 and 16.
The paper tray module of FIGS. 15 and 16 may correspond with the paper tray module 112 of FIGS. 7 and 8, but may be of substantially greater depth so that paper bin 180-1 of FIG. 16 may accommodate a substantially greater number of paper sheets, e.g. two hundred paper sheets instead of fifty.
In each of the embodiments of FIGS. 6-11 and 15 and 16, the printer module 350, FIG. 11, may be completely removed from the unit by vertically aligning limit pin 360 under disk 355, FIG. 11, and then lifting module 350 vertically so that pin 360 travels upwardly along channel 301a as the disk is lifted from its receiving recess 356, FIGS. 9 and 10. The electrical connections may be of the pin and socket type so as to readily severed, and readily reestablished.
It will be apparent that many modifications and variations may be made without departing from the scope of the teachings and concepts of the present invention.
DESCRIPTION 13 3 8 0 ~ 9 This invention is particularly concerned with printer devices such as are utilized in connection with product delivery e.g. to retail stores. In a field known as route accounting, a computerized terminal maintains price and quantity information concerning various items to be delivered at a series of stores, and a printer unit is utilized to produce a printed record for each customer. The printer may be carried into each store with the terminal, or the printer may be part of the fixed equipment within a delivery vehicle.
In a typical route accounting system, a portable modular printer device may comprise a briefcase containing the printer unit. Preferably such portable systems have a receptacle for plug-in coupling of a computerized terminal.
In the past, systems providing an eighty column printing capacity have utilized portable configurations representing relatively high cost beyond the cost of the basic printer unit, and adding very substantially to the basic weight of the printer.
It is conceived that it would be highly beneficial to create a portable printer system requiring only minimal additions in terms of cost and weight over that of the basic printer. It would be ideal if a modular standardized construction could be applicable also to non-portable printer systems and capable of readily receiving computerized terminals of different configuration.
Accordingly, it is a basic objective of the invention to provide a portable printer device which adds only minimal cost and weight to a basic printer unit.
A further object is to provide a modular printer device which is of particularly compact and convenient dimensions for portable use and yet which is readily 1~ ~ 8 ~ 49 73164-25 converted to use in non-portable applications such as are common in the route accounting field.
Another related object is to provide a basic standardized frame construction which is readily adapted to the reception of improved printer units and more compact computerized terminal configurations as such become economically feasible.
A particularly advantageous embodiment of the invention utilizes a standardized open frame construction for receiving a modular printer assembly and a modular terminal assembly. The frame may have an external configuration so as to snugly receive a carrying handle and/or other attachment suitable for a portable device, or to receive an auxiliary terminal mounting bracket facilitating use as a non-portable installation. A paper tray module for the printer unit may itself provide the bottom closure for the standard open frame, and serve with the frame as part of a water repellant encasement for the modular printer assembly. The printer housing module may accommodate one hundred and eighty degree reversal of the printer unit to adapt to portable or vehicle mounting. A low cost printer adapter means may adapt a printer housing module to different printer units, and a light weight economical terminal module may serve to adapt the standard frame to different size terminal configurations of a terminal family.
According to a broad aspect of the invention, there is provided in a modular printer system, a modular printer device for containing a computerized terminal for supplying data to be printed and a printer means for printing data supplied by a ,~

DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS
In FIG. 1, a unitary modular portable printer device 10 is shown as comprising a standardized open l33sa43 frame module 11 having a paper tray module 12 assembled therewith as bottom closure.
Eitting within the open frame 11 are a terminal module 14 with a hinged cover 15, and a printer module 16 having a paper outlet slot 16A which may be selectively covered by means of a laterally shiftable cover strip 17.
A carrying handle 18 is slidably engaged with an external side of the open frame 11.
As seen in FIG. 2, the open frame 11 is composed of four rectilinearly arranged frame elements 21-24 and a single additional frame element or crosspiece 25 subdividing the open frame to provide a terminal receptacle 26 and a printer receptacle 27.
As shown in FIG. 2, the terminal module 14 has downward directed horizontal surfaces such as 14A and 14B
at the four side thereof which are upwardly offset relative to a bottom 14C of the terminal module.
Vertically disposed side walls such as 14D and 14E extend from the outer perimeter of the bottom 14C to inner margins of the surfaces such as 14A and 14B. The terminal module 14 fits into receptacle 26 with surfaces such as 14A and 14B resting on four rectilinearly arranged ledge portions such as 23A and 24A which are provided by the frame elements 21, 23, 24 and 25. These ledge portions at their inner edges confront the terminal module side walls such as 14D and 14E when the terminal module is assembled therewith.
Thus the ledge portions such as 23A, 24A of the frame elements 21, 23, 24 and 25 may be taken as principally defining terminal module receptacle 26.
Similarly ledges such as 23A and 25A of frame elements 21, 22, 23 and 25 support upwardly offset surfaces such as 16A and 16B of printer module 16, and confront side walls such as 16C and 16D, and may be taken as essentially defining printer module receptacle 27.
_ 1338043 -6-The terminal module 14 releasably receives the computerized terminal 30 upon opening of cover 15. sy way of example the terminal module 14 may have an interior space of size to receive terminals known as the model 121XL and model 141XL of the Norand Corporation, Cedar Rapids, Iowa.
Such terminals 30 have a display region 31, a keyboard region 32 and a battery compartment region 33, and may be used for route accounting operations, for example. The terminal 30 may have an electrical interface at its end 35 which may comprise a 15-pin connector which mates with a mating connector within module 14 as the terminal is inserted into its module. A
terminal 30 may weigh about one kilogram including batteries, memory and communications adapter. As with present printers of Norand Corporation, the electrical interface at 35 and other constituents of terminal 30 may allow the supply of data to the terminal module interface for printing by means of the printer unit within printer module 16.
By way of example printer module 16 may be of interior configuration to receive a commercially avail-able eighty column printer which can print on three-ply fanfold paper supplied by the paper tray module 12, e.g.
paper having a width between 5.0 inches and 10.0 inches.
An example of such a printer is the Citizen MPS-20.
Paper tray module 12 may for example, for the portable device have a capacity of fifty sheets of three-ply paper. As an option for a non-portable ~evice as in FIG. 3, a paper tray module may have a capacity of two hundred three-ply sheets.
FIG. 2 shows the frame element 21 as including upper and lower flange portions 21A and 21B which have opposed edges overhanging a central body portion 21C so as to define a guideway 37 for receiving a slider member 38, FIG. 5, integral with the carrying handle 18. A
slmllar guldeway 39 ls deflned by flange portlons of the frame element 23.
In FIG. 3, the open frame 11 and paper tray 12 may be ldentlcal and yet provlde a non-portable subassembly 40 whlch may dlffer from portable devlce 10 by the absence of handle 18, and attachment of a slde arm bracket 41 to the frame 11. The bracket 41 may form a termlnal cradle wlth a termlnal module receptacle 42 recelvlng a termlnal module 14 ldentlcal to that recelved by portable devlce 10. The prlnter module receptacle 27 ls ldentlcal to that of the portable devlce 10, so as to recelve the prlnter module 16 ln the same orlentatlon as ln FIG.
1, or reversed as in FIG. 2. A second termlnal may be located at 42, FIG. 3, where lt may be automatlcally malntalned ln a charged condltlon by means of a charger connected wlth vehlcle power. A lockable llft-up cover of module 14 may retaln a termlnal 30 slmllarly to the way shown ln a brochure number 960-382-509 of Norand Corporatlon whlch has a 1985 copyrlght notlce and whlch relates to a data system for bakery dlstrlbutlon. The brochure provldes background lnformatlon as to exemplary functloning of the computerlzed termlnal 30 and of the lllustrated prlnter systems.
FIG. 4 shows a non-portable prlnter subassembly 40' ldentlcal to subassembly 40 except that the slde arm bracket 41 ls mounted on the left slde of the prlnter module receptacle 27 lnstead of the rlght slde as ln FIG. 3. In FIG. 4, the termlnal module receptacle 26 ls shown ready to recelve a second termlnal module so that two.termlnals such as 30 may be present where deslred. For example, one termlnal at 26 may be recharged whlle the second terminal 30 is removed from a terminal module 14 secured in receptacle 42 for use durlng dellvery to a retall store or the llke.
As best seen ln FIG. 4, the slde arm bracket 41 may have a sllder member 41A lntegral therewlth whlch is slldably engageable ln guldeway 37, FIG. 3, or guldeway 39, FIG. 4.
Sultable means, not shown, may retaln the handle or termlnal cradle ln assembled relatlonshlp to the frame, e.g. screws or the llke. Slmllarly, the termlnal and prlnter modules may be flxedly retalned with the open frame e.g. by threaded fasteners.

In this embodiment a printer cover 117 has a paper outlet slot 117A. A control panel 118 may include actuating regions such as "Advance Page" actuator 118A and a "Set Top of Page" actuator 118B.
The open frame 111 may have a configuration similar to that of frame 11 of FIG. 2, and in each embodiment the frame may be of integral unitary construction and of structural plastic material (e.g. Noryl FN-215) so as to provide the desired strength and rigidity with a minimum weight of material. Left and right frame elements 121 and 123 have upper and lower flange portions similar to flanges 21A, 21B, FIG. 2, which protectively embrace terminal module 114, printer module 116 and paper tray module 112.
As best seen in FIG. 7, frame elements 121 and 123 have central grooves which are shown as receiving an interior rib structure 130A of a foot member 130 and a base rib structure 140A of a handle member 140. Threaded fastening elements such as indicated at 141 and 142 in FIG. 8 may secure members 130 and 140 with the frame 111.
As seen FIG. 6, a base 140~ of handle member 140 may extend for the entire length of frame element 123 so as to completely cover the central groove therein.
As shown in FIG. 7, terminal module 114 has an elongated recess 114A accommodating reciprocal movement of a terminal retainer bracket lS0. A hand-held terminal corresponding to terminal 30, FIG. 2, is indicated in dash outline at 152, FIG. 7, in coupled relationship to the terminal module 114. The terminal 152 is disengaged 1338~9 -12-from the terminal module by sliding the retainer bracket 150 to the right as seen in FIG. 7, against the action of a spring means located in a bottom portion of the terminal module 114. The spring means acts on the bracket 150 with sufficient force to insure inter-engagement of a socket of the terminal 152 with a plug type connector 154 associated with the terminal module 114. Connector 154 is connected with the electric circuitry of the printer device 100 by means of a cable indicated at 160. As previously described, connector 154 and cable 160 provide for data communication between the terminal indicated at 152 and a printer unit associated with printer module 116.
As seen in FIG. 7, terminal module 114 is comprised of a terminal holder base 170 of molded plastic construction (e.g. Cycolac KJW, Borg Warner). The base 170 may be threadedly secured to bosses integral with the underlying frame elements corresponding elements 24 and 25, FIG. 2. The base 170 is provided with a double wall configuration at its opposite longitudinal ends such that the cable 160 may extend within an enclosed chamber 172.
As shown in FIG. 8, paper tray module 112 of the portable device 100 may be provided with a fifty sheet paper bin 180 for holding a supply of paper which is to be automatically fed into the printer mechanism. The paper tray 112-1 shown in FIG. 16 is equipped with a larger paper bin 180-1 capable of holding 200 sheets for automatic feed into a printer mechanism. The larger capacity paper tray module 112-1 is normally associated with a non-portable device such as shown in FIGS. 15 and 16. The paper tray modules 112 and 112-1 may be identical except for the difference in capacity of the paper bins.
As diagrammatically indicated in FIGS. 7, 9 and 10, terminal holder base 170 may have an integral depressed central bottom 190 (FIG. 7) with two integral upstanding _ 13380 49 -13-bosses 191, 192 (FIG. 9) serving to secure the ends of a tension spring indicated diagrammatically at 194. The bracket 150 includes an integral slider piece 200 with an integral depending lug 201 about which a mid region 194A

In the illustrated embodiment the control panel 118 includes an apertured structural member 270A which is an integral part of a one-piece printer case 270 of plastic material (e.g. Cycolac KJW, Borg Warner). The case is of generally open rectangular configuration and overlies four elements of the frame 111 (corresponding to frame elements 21, 22, 23, 25, FIG. 2). The case 270 includes a rectangular perimeter 271, FIG. 10, which continuously sealingly engages the sealing strip 240.
The frame 111 includes an integral crosspiece 280, FIG. 10, with integral tab portions such as 281, FIG. 10, having threaded sleeves to which overlying flanges such as 282 ( FIGS. 9 and 10) and 283 ( FIG. 9) of the printer case 270 are secured by means of screws such as 284.
Corner tabs 254 and 255, FIG. 8, of the frame 111 are threadably engaged with corner flange parts 287 ( FIGS.
8-10) and 288 ( FIG. 8 and 9) as indicated by screw 291, FIGS. 9 and 10.
The printer case 270 is provided with integral inwardly projecting ribs at opposite sides thereof which define printer module mounting means 301, 302, FIGS. 9 and 10. The purpose of mounting means 301, 302 is explained in detail hereafter in reference to FIG. 11.
As seen in FIG.10, each of the mounting means includes a vertical guide channel such as 301A connecting with an arcuate guide channel such as 301B.
As seen in FIG. 8, a rear wall element 270B of the printer case 270 has a series of five notches leaving exposed ledges such as 311 which interengage with hook parts integral with vertical ribs such as 312, FIG. 10.
This provides for a hinged coupling of the rear wall 117B
of cover 117 with the rear wall 270s of the printer case, the frontal edge of cover 117 having a series of cam hooks such as 31~ which can be snapped into engagement with an edge 315 of the printer case 270. When the cover 117 is opened, it ~an be completely removed by pulling the integral hooks of ribs 312 forwardly out of the notches 310.
The rear wall element 270B, FIG. 10, has a sealing strip 320 secured thereon which engages with a lower edge of cover wall 117B when the cover 117 is in closed position. The cover 117 has a further sealing strip 321 which together with sealing strip 320 extends along the entire closure perimeter of the cover 117. A clear soft plastic strip 330 may be secured in a recess 331, FIG. 6, e.g. by means of adhesive at 332, FIG. 10, so that a flap 330A of strip 330 normally covers the paper outlet slot 117A while still allowing paper to be fed therefrom during printing operation.
FIG. 11 shows a printer module 350 interengaged with the printer case 270. In particular the printer module is provided with a generally u-shaped pivot frame 351 of pressed metal which adapts various commercially available printer mechanisms such as 352 to the printer case 270.
The pivot frame 351 has upstanding lateral flanges such as 351A each of which carries a pivot shaft with a disk 355 which fits into a conforming receiving slot such as indicated at 356, FIG. 10, of the printer module mounting means 301, 302, FIG. 9. A limit pin 360, FIG.
11, of each pivot frame lateral flange is of lesser diameter than disk 355 so as to be freely movable in the vertical channel 301A and in the arcuate channel 301B, FIG. 10.
The pivot frame 351 of the printer module 350 is further provided with a pair of longitudinally extending flanges such as 351B which carry rotary latch mechanisms 361. The latch mechanisms each include a sleeve 362 which has an extended position as indicated in dot dash outline at 362-1 and which is shiftable against the action of a compression spring 364 as the printer module pivots clockwise as shown in FIG. 11 from the inactive position 350-1 to the position shown in solid lines at 350. As the sleeve 362 retracts a bar-shaped lug 366 moves through a conforming elongated slot such as 367 in a tab such as 288, FIG. 9. When lug 366 reaches a position below the tab 288, a camming action between sleeve 362 and the lug stem may cause the lug 366 to rotate slightly and interlock with the tab. To release the lug 366, the printer module is rocked slightly in the clockwise direction against the action of spring 364, whereupon the lug 366 is realigned with its slot 367 to allow counterclockwise pivotal movement of the printer module to position 350-l.
The pivot frame 350 further includes a çentral curved extension 351C disposed between the longitudinal flanges 351B and providing a smooth paper guide face 370 which forms part of a paper feed path 371. When the printer module is pivoted to position 350-1, the paper path may be extended as indicated at 371-1.
