An image forming apparatus to which the present invention is applied will be described.
FIG. 1 is a perspective view of a copying machine 2 that is an image forming apparatus according to the present embodiment.
The copying machine 2 includes an apparatus main body 4, an image reading apparatus 40 disposed above the apparatus main body 4, an openable / closable pressing plate 6 provided on the upper surface of the image reading apparatus 40, and an operation panel 8. In the lower part of the apparatus main body 4 of the copying machine 2, there are a first paper feed cassette 10 and a second paper feed cassette 12 that can be inserted and removed. An in-body discharge section 14 is formed between the apparatus main body 4, the pressing plate 6, and the image reading apparatus 40.

FIG. 2 is a schematic explanatory diagram of the apparatus main body 4.
Hereinafter, the image forming process in the apparatus main body 4 will be described.
After the surface of the drum-shaped photoconductor 1 as the latent image carrier is uniformly charged by the charging device 5 as the charging means, the surface of the photoconductor 1 is exposed on the surface of the photoconductor 1 by the exposure device 9 as the exposure means based on the image information. An electrostatic latent image is formed. The electrostatic latent image is visualized as a toner image by a developing device 3 as developing means, and the toner image on the surface of the photoreceptor 1 is transferred to a transfer nip that is a facing portion of the transfer roller 7 and the photoreceptor 1 as transfer means. To reach.

On the other hand, the transfer paper P, which is a recording medium supplied from either the first paper feed cassette 10 or the second paper feed cassette 12, is temporarily stopped by the registration roller pair 21, and the toner image on the photoconductor 1 is transferred to the transfer nip. The paper is conveyed toward the transfer nip in accordance with the arrival timing. An arrow “R” in FIG. 2 indicates the path of the transfer paper P.
In the transfer nip, the toner image on the photoreceptor 1 is transferred to the transfer paper P, and the toner image is fixed to the transfer paper P to which the toner image has been transferred by the fixing device 13 serving as fixing means. Thereafter, the transfer sheet P on which the toner image is fixed is discharged to the in-body discharge unit 14 by the discharge roller pair 23, and the image forming process for the transfer sheet P is completed.
As shown in FIG. 2, a toner bottle 11 that contains toner to be supplied to the developing device 3 is provided on the upper left side of the developing device 3 of the apparatus main body 4 in FIG. 2.

As shown in FIG. 1, the outer surface of the apparatus body 4 is covered with a plurality of exterior covers such as a front exterior cover 16, a front upper exterior cover 18, and a right exterior cover 17.
Inside the front upper exterior cover 18 is provided with a human body detection sensor unit 120 that supports a human body detection sensor 20 as a human body detection means, and a portion for detecting infrared rays of the human body detection sensor 20 is provided to be exposed outside the apparatus. ing. In the state shown in FIG. 1, the detection unit of the human body detection sensor 20 faces the front direction of the copying machine 2 and can detect the approach of a person from the front direction.

In an image forming apparatus such as the copying machine 2, in order to realize energy saving, when the apparatus is not used, a method of waiting in a power consumption state smaller than the power consumption amount when used is generally used. For example, when the unused time reaches a predetermined time, the control is automatically shifted to the standby mode. That is, the operating state of the apparatus is changed from the image forming mode to the standby mode.
In recent years, the number of applications used in image forming apparatuses has increased, and it has taken a long time to restore the controller. In view of this, a technique has been considered in which the human body detection sensor detects that the user is approaching the image forming apparatus, and the waiting time is reduced as much as possible by returning from the standby mode before the user starts the operation.

The copying machine 2 of the present embodiment shown in FIG. 1 is also provided with a human body detection sensor 20 from this viewpoint.
FIG. 3 is a block diagram showing an outline of a control system of the copying machine 2 according to this embodiment.
When the unused time reaches a predetermined time, the control unit 100 of the copying machine 2 performs control to shift to a standby mode in which power supplied to each unit of the apparatus main body 4 and power supplied to the image reading device 40 are reduced. In the standby mode, the human body detection sensor 20 performs a detection operation. When the human body detection sensor 20 detects the approach of the user, the standby mode is canceled and the image forming mode is entered. Thereby, before the user starts the operation on the operation panel 8, the transition to the image forming mode is started, and the waiting time until the image formation based on the user operation is performed can be reduced.

  In the copying machine 2 of the present embodiment, the human body detection sensor unit 120 holds the human body detection sensor 20. The human body detection sensor unit 120 is arranged on the front upper exterior cover 18 disposed on the front surface, which is the side surface on which the operation panel 8 is disposed, on the four side surfaces of the copying machine 2, and on the right side surface on the right side. The front upper cover right corner 19 between the right outer cover 17 and the right outer cover 17 is arranged. Furthermore, the human body detection sensor unit 120 that holds the human body detection sensor 20 is configured to be rotatable in the horizontal direction around a rotation shaft extending in the vertical direction.

Here, a reference example of the copying machine 2 in which the detection range by the human body detection means cannot be changed will be described.
FIG. 15 is a perspective view of the copying machine 2 of the reference example in which the human body detection sensor 20 is fixed to the apparatus main body 4.
The copying machine 2 of the reference example shown in FIG. 15 is the same as the copying machine 2 of the embodiment shown in FIG. 1 except that the human body detection sensor 20 is fixed to the apparatus main body 4. The sensor 20 will be described.

The human body detection sensor 20 is disposed in the vicinity of the front operation panel 8 on the operation side of the apparatus body 4 in terms of position. Two human body detection sensors 20 are arranged, and the respective light receiving portions are arranged obliquely downward and facing each other so that the positions of the incident angles (viewing angle “θ”) are different from each other. (See FIG. 16 for details).
By arranging in this way, the entire viewing angle can be made wider than when only one human body detection sensor 20 is used, and the space for securing the field of view can be shared by facing inward, thereby saving space. Can be planned.

  The human body detection sensor 20 can detect a user approaching from a longer distance when the human body detection sensor 20 is arranged at a high position in the apparatus body 4. Further, since the user generally accesses the operation panel 8 when using the apparatus, if the human body detection sensor 20 is attached near the height of the operation panel 8, the detection distance from the apparatus main body 4 is sufficient. As well as earning money, it is possible to accurately detect the user who uses the device.

  FIG. 16 is an explanatory view of the exterior cover (front upper exterior cover 18) to which the human body detection sensor 20 is attached in the copying machine 2 of the reference example as viewed from the outside. As shown in FIG. 16, the front upper exterior cover 18 is integrally formed with a sensor holding part 22 in which two light receiving part insertion holes 22a into which the sensor light receiving part 20a of the human body detection sensor 20 is fitted are formed. Two human body detection sensors 20 are set from the inside of the sensor holding portion 22, and each hemispherical sensor light receiving portion 20a is inserted into the light receiving portion insertion hole 22a and fixed in a state protruding outward from the light receiving portion insertion hole 22a.

FIG. 17A is a side view, and FIG. 17B is a top view. As described above, since the human body detection sensor 20 is disposed obliquely downward, the predetermined range in front of the copying machine 2 is the human body detection range α. In the state shown in FIG. 17, since the user U is located outside the human body detection range α, the human body detection sensor 20 does not detect the user U.

  As shown in FIG. 15, in the copying machine 2 of the reference example, the human body detection sensor 20 is installed with the orientation fixed toward the front direction of the copying machine 2. In this installed state, the human body detection sensor 20 can detect the approach of the user U from the front, but has a blind spot for the approach from the side.

At this time, the rotation center of the human body detection sensor unit 120 is located near the center of the human body detection sensor unit 120.

  FIG. 8 is a top view showing the position of the unit rotation center 120r which is the rotation center of the human body detection sensor unit 120 in the copying machine 2. As shown in FIG. FIG. 8 shows a state in which the human body detection sensor 20 of the human body detection sensor unit 120 arranged at the front right end of the copying machine 2 faces the front side. In FIG. 8, out of the external shape of the human body detection sensor unit 120, the external shape (the external shape on the back side and the left side surface) located inside the copying machine 2 is indicated by a broken line (hidden line).

A distance “A1” in FIG. 8 is a distance from the unit rotation center 120r to the front of the human body detection sensor unit 120, and a distance “A2” in FIG. 8 is a human body detection sensor unit 120 from the unit rotation center 120r.

This is the distance to the left side surface of the sensor unit 120.
In the copying machine 2 of the present embodiment, the unit rotation center 120r is disposed at the center of the human body detection sensor unit 120, and therefore “A1” = “A2” = “B1” = “B2”.

In the copying machine 2, a sensor unit rotation shaft 123 is disposed on the exterior or frame of the apparatus body 4, and the human body detection sensor unit 120 is installed on the sensor unit rotation shaft 123. An E-ring groove 123a is provided at the tip of the sensor unit rotation shaft 123, and the human body detection sensor unit 120 can be held by installing it with a fastener such as an E ring after the human body detection sensor unit 120 is mounted.
As shown in FIG. 6, the sensor unit cover 121 is provided with a front convex shape 121d. With the front convex shape 121d, when the user rotates the human body detection sensor unit 120, the front convex shape 121d serves as a handle, and the human body detection sensor unit 120 is easily rotated.

Next, the rotation operation of the human body detection sensor unit 120 will be described.

FIG. 8 described above is a top view of a state in which the sensor light receiving unit 20a of the human body detection sensor 20 faces the front.

  In the state shown in FIG. 9, two exposed side surfaces of the four side surfaces of the human body detection sensor unit 120 are flush with the surface of the front upper exterior cover 18 or the surface of the right exterior cover 17 of the copying machine 2. It is arranged to be on the top, enhancing the appearance quality. In the state shown in FIG. 9, the sensor light receiving unit 20 a protrudes forward of the apparatus from the surface of the front upper exterior cover 18. By projecting the sensor light receiving unit 20a from the exterior surface of the front surface of the copying machine 2, the outer surface of the apparatus main body 4 is prevented from interfering with the path of infrared rays incident on the sensor light receiving unit 20a of the human body detection sensor 20. The human body detection range α can be widened.

  As shown in FIGS. 8 and 9, by directing the sensor light receiving unit 20a to the front of the apparatus on which the operation panel 8 is arranged, the user U who has approached the operation panel 8 from the front of the apparatus is detected by the human body detection sensor 20. Can be detected. As a result, in an installation environment where the frequency of the user U approaching from the front of the apparatus is high, the approaching user U starts the return operation from the standby mode to the image forming mode before operating the operation panel 8. be able to.

  FIG. 10 shows the human body detection of the copying machine 2 in a state where the angle of the human body detection sensor unit 120 is set obliquely so that the sensor light receiving unit 20a of the human body detection sensor 20 faces diagonally to the right side with respect to the front of the copying machine 2. FIG. 3 is an enlarged explanatory view in the vicinity of a sensor unit 120. FIG. 10A is a perspective view, FIG. 10B is a top view, and FIG. 10C is a side view as seen from the side of the human body detection sensor unit 120 (the diagonally right rear side of the copying machine 2). FIG. 11 is a top view of the vicinity of the right front corner of the copying machine 2 in the state shown in FIG.

  As shown in FIGS. 9A, 10A, and 10C, the lower portion of the human body detection sensor unit 120 of the front upper cover right corner 19 is a chamfered portion 125 that is chamfered. Yes. By having the chamfered portion 125, even if the sensor light receiving unit 20a is installed in the diagonally right side with respect to the front of the copying machine 2, as shown in FIG. It can suppress that the corner | angular part of the apparatus main body 4 interferes with the passage route of the infrared rays which inject into 20a. As a result, the human body detection range α can be widened.

  FIG. 12 is an enlarged explanatory view of a state in which the sensor light receiving unit 20 a of the human body detection sensor 20 faces the right side surface of the copying machine 2. 12A is a perspective view, and FIG. 12B is a front view of the copying machine 2 as viewed from the front side. 13 is a top view of the vicinity of the front right corner of the copying machine 2 in the state shown in FIG.

  In the state shown in FIG. 12, two exposed side surfaces among the four side surfaces of the human body detection sensor unit 120 are flush with the surface of the front upper exterior cover 18 or the surface of the right exterior cover 17 of the copying machine 2. It is arranged to be on the top, enhancing the appearance quality. In the state shown in FIG. 12, the sensor light receiving unit 20 a protrudes to the right of the apparatus from the surface of the right outer cover 17. Since the sensor light receiving unit 20a protrudes from the outer surface on the right side of the copying machine 2, the outer surface of the apparatus main body 4 is prevented from interfering with the path of infrared rays incident on the sensor light receiving unit 20a of the human body detection sensor 20. The human body detection range α can be widened.

  As shown in FIGS. 12 and 13, the human body detection sensor 20 can detect the user U approaching to operate the operation panel 8 from the right side of the apparatus by directing the sensor light receiving unit 20 a toward the right side of the apparatus. . Thereby, in the case of an installation environment where the user U approaches frequently from the right side of the apparatus, the approaching user U starts the return operation from the standby mode to the image forming mode before operating the operation panel 8. can do.

In the copying machine 2 of the present embodiment, by rotating the human body detection sensor unit 120, the direction in which the sensor light receiving unit 20a of the human body detection sensor 20 faces (the detection direction of the human body detection sensor 20) is changed from the front of the apparatus to the right side of the apparatus. Can be displaced between. And the malfunction which cannot detect a user's approach can be suppressed by directing the sensor light-receiving part 20a to the direction where a user approaches frequently.
It is good also as a structure provided with the fixing means which fixes the direction of the human body detection sensor unit 120 rotatable with respect to the apparatus main body 4. FIG. By fixing the orientation of the human body detection sensor unit 120 with the fixing means in a state where the sensor light receiving unit 20a is directed in a direction in which the user approaches frequently, the human body detection sensor unit is caused by vibration or the like during operation of the copying machine 2. It is possible to prevent the orientation of 120 from changing.

  The copying machine 2 according to the embodiment includes an apparatus main body 4, an external cover such as a front external cover 16, a front upper external cover 18, and a right external cover 17 that cover an outer surface of the apparatus main body 4, and a human body detection sensor 20 that is a human body detection unit. With. The human body detection sensor 20 includes a pyroelectric element that generates an output signal in accordance with the amount of change in incident infrared rays. The copying machine 2 of the present embodiment is configured to use a pyroelectric element as the human body detection sensor 20, but the human body detection sensor 20 receives infrared rays, such as a detection sensor that emits infrared rays and receives reflected light. Another detection sensor may be used. Furthermore, the human body detection sensor 20 is not limited to one using infrared rays, but may be any one that can detect the approach of a person from the detection direction, such as one using ultrasonic waves or visible light.

Further, the copying machine 2 includes a control unit 100 that is a control unit that changes the operating state of the copying machine 2 based on the output of the human body detection sensor 20. Further, the human body detection sensor unit 120 that holds the human body detection sensor 20 is configured by the sensor unit cover 121 and the sensor unit housing 122.
The human body detection sensor unit 120 is provided on the front upper cover right corner portion 19 which is a corner portion between the device front side where the operation panel 8 which is an operation portion is disposed and the device right side surface which is the side surface of the device front. It is arranged and is rotatable with respect to the apparatus body 4.

  As in the copying machine 2 of the reference example, a configuration in which a human body detection sensor is installed in front of the image forming apparatus is known. In this configuration, the human body detection sensor unit 120 can detect the approach of the user from the front direction of the apparatus, but has a blind spot for the approach of the user from the lateral direction of the apparatus. Depending on how the user uses it, as shown in FIG. 18, the image forming apparatus may be installed along a narrow (elongated) room. In this case, since the user approaches from the side of the apparatus, there is a case where the user is not detected, and there is a problem that the human detection sensor at the corner does not function.

  On the other hand, in the copying machine 2 of the embodiment, the human body detection sensor 20 is disposed at the front upper cover right corner 19 which is a corner of the copying machine 2 and is rotatable. Therefore, when the copying machine 2 is installed so that the apparatus is along a narrow (elongated) room, the human body detection sensor 20 can be rotated to change the detection direction of the human body detection sensor 20 in the copying machine 2. . Therefore, it is possible to set to detect the approach of the user from the side surface direction of the copying machine 2.

  Further, the human body detection sensor 20 sets the detection distance by being arranged downward. In order to make the detection distance constant before and after the rotation, the rotation direction needs to be horizontal. On the other hand, since the human body detection sensor unit 120 can be rotated in the horizontal direction, the copying machine 2 according to the present embodiment maintains the intended setting for the detection distance of the human body detection sensor 20. 2, the detection direction of the human body detection sensor 20 can be changed.

  If the outer surface of the human body detection sensor unit 120 is out of alignment with the surface of the exterior cover before and after the rotation and the outer surface of the human body detection sensor unit 120 protrudes, the appearance quality deteriorates. On the other hand, in the copying machine 2 of the present embodiment, the unit rotation center 120r is located at the center of the human body detection sensor unit 120. As a result, as shown in FIGS. 8 and 13, the step between the outer surface of the human body detection sensor unit 120 and the surface of the exterior cover of the apparatus body 4 can be eliminated before and after the rotation of the human body detection sensor unit 120. Quality can be improved.

  When the human body detection sensor 20 is manually rotated, if the rotating member has a convex portion, it is easy to rotate. On the other hand, the copying machine 2 of the present embodiment has a front convex shape 121d that functions as a handle on the outer surface of the human body detection sensor unit 120. By having a shape that functions as a handle, it is possible to easily rotate the human body detection sensor 20 when the human body detection sensor 20 is manually rotated.
