Description

[Detailed description of the invention] (Field of the invention) The invention is a remote control that can be used, for example, to lock and unlock car doors, or unlock the glass door or wooden frame of a pachinko machine without contact. Regarding equipment.

(Prior art and its problems) In this type of device, when the battery is removed during battery replacement, the memory (e.g.
Because data such as unique key codes stored in the RAM (RAM) disappears, a capacitor is generally used to maintain it at a predetermined potential.

However, in the case of the conventional example with such a configuration, when replacing the battery, the user accidentally touches and operates the transmitter switch, causing the infrared light emitting diode to emit light and discharging the charge accumulated in the capacitor. This was inconvenient in practical terms, as the data stored in the RAM would disappear, making it impossible to perform certain operations and requiring the data to be rewritten.

(Purpose of the invention) The present invention was developed in view of the above circumstances, and is designed to avoid accidental operation of the transmitter switch when replacing the battery, and to effectively prevent data stored in the memory from disappearing. The purpose is to

(Structure and effects of the invention) In order to achieve the above purpose, the invention has the following features:
In a remote control device, a battery cover is attached to a main body case so as to be slidable between a position where the battery compartment is closed and a position where the battery compartment is opened and a transmission switch is covered to prevent operation of the transmission switch. establish.

According to this configuration, when replacing the battery, the transmitting switch is covered by the battery cover that is opened for the purpose of replacing the battery, thereby preventing accidental touching of the transmitting switch.

Therefore, you can definitely avoid accidentally operating the transmitter switch when replacing the battery and thereby erasing the data stored in the memory, and you can be careful not to touch the transmitter switch when replacing the batteries. It has now become possible to provide an infrared remote control device that is extremely convenient in practice, as it eliminates the need for rewriting due to data loss.

In addition, since the battery cover remains attached to the main body case in the position covering the transmitter switch with the battery compartment open, the battery cover does not separate from the main body case, and if the battery cover is accidentally dropped and lost. It has the advantage of avoiding accidents.

(Description of Embodiments) Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings. FIG. 1 is an overall exploded perspective view of an infrared remote control device according to an embodiment of the present invention, and FIG. 2 is an overall external perspective view as viewed from the opposite direction from FIG. 1.

In these figures, 1 is the main body case,
It is composed of an upper case 1a and a lower case 1b.

Inside the main body case 1 is a printed circuit board 5 on which various electronic components such as a microcomputer 2, switching elements 3, an infrared light emitting diode 4, etc. are attached. Reference numeral 6 denotes a light-transmitting member through which the infrared light emitted from the infrared light emitting diode 4 passes, and is attached to one longitudinal end of the main body case 1, and the other longitudinal end has an opening 7 for attaching to a key chain or the like. is attached.

Reference numerals 8 and 8 indicate button batteries, respectively, and a battery housing section 9 accommodates the button batteries 8 and 8, respectively.
is constituted by a hole formed near the longitudinal center of the upper case 1a.

The outer surface of each of the longitudinally opposite end portions of the upper case 1a protrudes from the outer surface of the portion where the battery accommodating portions 9, 9 are formed, and the switching elements 3, 3 are operated from the outside at the portion on the transparent member 6 side. Switch hole 1 facing the transmitting switch 10, 10
1 and 11 are formed.

The main body case 1 has a sliding plate at a position where the battery housing parts 9, 9 are closed, and at a position where the transmission switches 10, 10 are covered and their operation is prevented on the transparent member 6 side. A battery cover 12 is attached so as to be freely movable.

As shown in FIG. 3, the outer surface of each of the transmitting switches 10, 10 is located substantially flush with the outer surface around the switch hole 11 of the upper case 1a, or located further inward of the main case 1, battery cover 1
When the battery cover 12 is slid to a position where the battery housing parts 9, 9 are opened, the inner surface of the battery cover 12 covers the transmitting switches 10, 10 without coming into contact with them.

Further, as shown in FIG. 4, recesses 13a, 13a, 13b, 13b are formed near the sides of the battery housing parts 9, 9 and the transmitting switches 10, 10, respectively, on both side end faces of the main body case 1,
On the other hand, protrusions 14, 14, which are elastically fitted into the recesses 13a, 13a, 13b, 13b, are protrudingly provided at predetermined locations on the inner surface of the battery cover 12.
In the state where the projections 14, 14 close the recess 13,
a, 13a, and on the other hand, when the battery housing parts 9, 9 are open, the protrusions 14, 1
4 elastically fits into the other recesses 13b, 13b,
It is configured to be fixedly maintained at a position covering the transmitting switches 10, 10.

As shown in FIG. 5, a capacitor 15 is connected to the microcomputer 2 in parallel with the button batteries 8, 8, and when the transmission switch 10 is closed, a switching transistor Tr is connected.
When the button batteries 8, 8 are replaced, the charge accumulated in the capacitor 15 causes the RAM constituting the microcomputer 2 to emit light.
(not shown).

When replacing the button batteries 8, 8, the transmission switches 10, 10 are covered to prevent operation thereof, thereby preventing the capacitor 15 from discharging as the light emitting diode 4 emits light. .

16, 16, hook the battery cover 1 with your fingertips.
These are wavy portions formed on both lateral outer surfaces of the battery cover 12 to facilitate sliding operation of the battery cover 12.

In the above embodiment, the battery accommodating parts 9, 9 and the transmitting switches 10, 10 are connected to each other in the main body case 1.
Since the switching elements 3, 3 and the electrode terminals can be attached to the printed circuit board 5 from the same direction, this has the advantage of improving manufacturing productivity and being inexpensive. There are, but
In the present invention, for example, the battery accommodating parts 9, 9 and the transmitting switches 10, 10 are respectively connected to the main body case 1.
