Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of an operating push button used in electronic equipment such as an electrophotographic copying machine.

[Background of the invention]

The operation panel of an electrophotographic copying machine is provided with operation buttons that are frequently used by the user when copying and operation buttons that are used extremely infrequently.

The latter operation buttons are usually grouped together on one side of the panel and covered by a transparent cover that can be opened and closed to prevent accidental touching.

[Problem that the invention seeks to solve]

From the standpoint of design and handling, it is preferable that the height of the top surface of this cover corresponds to the top surface of the operation buttons that are commonly used. A difference in level occurs.

Therefore, separate substrates for mounting the switch members operated by the operation buttons must be prepared in two different heights, resulting in a large cost burden.

As a result of solving this problem and improving it, the present invention provides an operation push button structure that allows a common switch member on the same board to be operated by push buttons on operation panel surfaces of different heights for the reasons mentioned above. The purpose is to provide

[Means for solving problems]

The above purpose is to use push buttons on the panel surface of at least one component in the operating section of equipment that are located at different heights to be pressed on the same board via actuators that have different heights. This is achieved by the structure of the operation push button characterized in that it is configured to operate an attached common switch member.

〔Example〕

An embodiment of the present invention is shown in FIGS. 1 to 4.

This embodiment is directed to an operation section provided on the front upper surface of an electrophotographic copying machine as shown in FIG.

10 is a panel surface provided with push buttons and displays that are frequently used by the user when copying, 20 is a panel surface provided with push buttons and displays that are rarely used, and 30 is a panel surface that covers the panel surface 20 and can be freely opened and closed manually. It is a transparent cover part.

In FIG. 1, 11 on the panel surface 10 is a copy button;
12 is a numeric keypad; 13 is an auto return button; 14 is a cassette size selection button; 21 on the panel surface 20 is a magnification selection button; 22 and 23 are enlargement and reduction buttons;
is a copy density switching button, etc.

The upper surfaces of the panel surface 10 and the cover member 30 are formed at the same height in order to make the appearance uniform and improve operability. Therefore, the thickness of the panel surface 20 is smaller than that of the cover member 30 than the panel surface IO. It is located at a lower position corresponding to the height of the

Figure 2 shows the cross section indicated by the arrow AA, and shows IOA and 20
A represents the panel surface 10 and the panel surface 20, respectively.
Continuous ground planes constituting IIA, 12A, 13A
, 14A, 21A, 22A, 23A, and 24A are actuators for the push buttons on the panel surface IQ and the panel surface 20 described above, which are inserted into the square holes provided in the base plate so as to be movable up and down, and are used for adhesion of vinyl sheets, which will be described later. It is held in the illustrated state by the support of the switch member.

Among the actuators, the actuators 21A, 22A, 23A, 24A attached to the panel surface 20 are the same as the actuators 11A, 12A attached to the panel surface 10.
, 13A.

14A, both of them are formed to have a height that is shorter than that corresponding to the height difference between the base plates 10A and 20A.

10B and 20B are vinyl sheets with numbers, symbols, codes, etc. pasted on the top surface of each of the boards 10A and 20A, and the vinyl sheets 10B and 2
Each actuator is pressed and activated via 0B.

That is, each push button 11, 12, 13, 14 on the panel surface 10
is each tall actuator and the vinyl sheet 10
B also presses each push button 21, 22, 23 . on the panel surface 20.
24 is constituted by each short actuator and the vinyl sheet 20B, but the pressing surface of each push button, that is, the working surface of each actuator, that is, the lower end surface is all kept at the same level.

Reference numeral 40 denotes a board for operation operated by each of the push buttons, which alone has a size that occupies the entire lower surface of the panel surface 10 and the panel surface 2o. A pair of spacers are provided for fixation.

11B, 12B, 13B, 14B and 21B, 22B
, 23B, and 24B are switch members operated by the actuators corresponding to the respective numbers, which are attached to the top surface of the board 4o, and whose ON-OFF signals are sent to the copying machine via printed wiring on the board 4o. Sent to the main unit's control device.

Each of the switch members can be set to 0N- by pressing the upper part.
Since the operating surfaces of each actuator mentioned above are all kept at the same level because they are turned off, it is possible to use a common or similar type of switch member.

Further, in FIG. 1 or FIG. 3 showing the cross section indicated by arrow BB, 50 is a pair of bearing members that are press-fitted and fixed into holes provided on the rear side of the main plate 20A, while 3OA is a pair of bearing members that are fixed by press-fitting into holes provided on the rear side of the base plate 20A, A pair of falling parts are integrally molded, and the round hole provided in the falling part 30A is press-fitted into a pin-shaped protrusion provided on the side surface of the bearing member 50 with appropriate pressure. The cover member 30 is the bearing member 5
It is rotatably supported at 0.

51 is a rod-shaped elastic member formed by bending piano wire or the like in several places, and has a free shape as shown in FIG. 3(b).
It is housed in the lower surface of the OA, and its top part passes through the hole H of the base plate 20A and comes into pressure contact with the inner surface of the cover member 30, urging the cover member 30 clockwise in FIG. 3(a).

Reference numeral 52 denotes a holding plate that locks the elastic member 51 and presses and fixes it to the lower surface of the base plate 20A. Reference numeral 53 denotes a pair of supports to which the nucleus layer plate is attached.

Reference numeral 54 denotes a hook member attached to the main plate 20A, and when the cover member 30 is in the closed position, the hole provided in the cover member 30 is retained in the closed position. When the lock is released, the cover member 30 opens at the angle indicated by the dashed line and comes into contact with the stepped portion of the base plate 2OA and is stopped.

Therefore, if the cover member 30 is further strongly pushed in the opening direction from the position shown by the dashed line, the cover member 30 will be disconnected from the bearing member 50 and separated from the operation panel surface 20 until it breaks. . At this time, since both the bearing member 50 and the elastic member 51 are left on the operation panel surface 20 side, the cover member 30 can be easily attached again to the supporting state.

〔Effect of the invention〕

According to the present invention, in addition to using a single common board for the operation board used for two operation panel surfaces having a difference in level, it is also possible to share a plurality of switch members or actuator members mounted on the board. The present invention provides an operating copper structure that can be used to provide a low-cost electrophotographic copier and other electronic equipment that significantly reduces component and assembly costs.
