Abstract

PURPOSE:To prevent operational touch from getting uncomfortable because a bracket which supports a switch assembling body is bent and a gap from being made between the bracket and a switch hole because the bracket is bent in the case of operating a switch button. CONSTITUTION:The bracket 23 is provided in the internal equipment of an equipment main body 10. The bracket 23, where a switch attaching hole is formed by piercing a plate surface and the assembling body 18 is fitted in the hole, supports the assembling body 18. The internal equipment of the main body 10 is covered with an outside cover 13 and the switch button 19 of the assembling body 18 is exposed from the switch hole 12a of the cover 13. Meanwhile, a rib 30 which is pressed by the operational force of the button 19 when the button 19 is operated and prevents the bracket 23 from being bent inside is provided on the cover 13 to turn inward from the cover 13.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a copying machine, printer,
Facsimile, shredder, etc.
The present invention relates to an electric / electronic device including a switch button to turn off.

[0002]

2. Description of the Related Art Conventionally, in a copying machine, for example, as shown in FIG. 5, a switch assembly 2 is fitted in a switch mounting hole 1a penetrating a plate surface of a bracket 1 and supported by the bracket 1. There is a configuration in which the bracket 1 is provided on an internal device of the device main body, the internal device is covered with an exterior cover (not shown), and the switch button 3 of the switch assembly 2 is exposed from a switch hole of the exterior cover.

When the power is turned on and off, the switch button 3 exposed to the outside is put on a finger and strongly pressed to operate it.

[0004]

However, in the conventional copying machine, when the switch button 3 is operated, the bracket 1 is flexed inward by being pushed by the force pressing the switch button 3, which causes a bad operation feeling. Yes, also bracket 1
As a result of the bending, a gap is created between the switch hole of the exterior cover and the bracket 1, which is not desirable in appearance and foreign matter may fall into the interior through the gap.

Therefore, an object of the present invention is, in the above-mentioned copying machine, that the bracket is bent when the switch button is operated and the operation feeling is not good, and the bracket 1 is bent so that the switch hole of the exterior cover and the bracket are not formed. The purpose is to prevent a foreign substance from falling into the interior from the gap due to the formation of a gap therebetween which is not desirable in appearance.

[0006]

Therefore, the present invention provides
For example, as shown in the following illustrated embodiments, in an electric / electronic device in which an internal device is covered with an outer cover 13 and a switch button 19 of a switch assembly 18 is exposed from a switch hole 12a of the outer cover 13, a bracket is attached to the inner device. 23, the bracket 23 supports the switch assembly 18, and the switch button 19
The exterior cover 13 is provided with ribs 30 that prevent the bracket 23 from bending when the bracket is operated.

[0007]

The ribs 30 prevent the bracket 23 from bending when the switch button 19 is operated.

[0008]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 4 is an external perspective view of the entire copying machine which is an embodiment of the present invention.

Reference numeral 10 in the figure denotes a device body. The device main body 10 is formed by covering the internal device with an outer cover 13 to form a box-shaped outer shape. A protrusion 10a is provided on the upper front surface of the device body 10, and an operation display unit 14 is provided on the top surface of the protrusion 10a. Further, a contact glass (not shown) on which an original is placed is provided on the upper surface of the device body 10, and an original pressing cover 15 for covering the contact glass is provided. The document pressing cover 15 is formed in a plate shape slightly larger than the contact glass and is provided so as to be openable and closable with respect to the apparatus body 10 via a hinge (not shown). Further, the left side of the device body 10 in the drawing, that is, the side surface outer cover 12, is provided with a sheet ejection port 16 for recorded sheets, and a sheet ejection tray 17 is detachably provided there. A switch button 19 of the switch assembly 18 is provided on the upper part of the side.

When performing recording by using this copying machine, first, the switch button 19 is put on with a finger, and the switch button 19 is strongly pressed to turn on the power. Then, the document holding cover 15 is opened, the document is placed on a contact glass (not shown) and set, and then the document holding cover 15 is closed again to hold the document, and the start button in the operation display unit 14 is pushed.
Then, while reading the image on the original, a read image is formed on the photoconductor by repeating the electrophotographic process such as charging, writing, developing, transferring, and cleaning, and a sheet fed out from a paper feeding cassette (not shown) is formed. The image on the photoconductor is transferred and recorded. After that recording,
The sheets are discharged from the sheet discharge port 16 and stacked on the sheet discharge tray 17.

In the copying machine described above, the peripheral portion of the switch assembly 18 is constructed in detail as shown in FIG. Reference numeral 23 in the drawing is a bracket. The bracket 23 is made of a metal plate, and as shown in FIG. 2, the base end portion 23a is bent at a right angle to form an entire L shape, and the tip end portion 23b penetrates the plate surface to form a switch mounting hole 23c. Provide vertically. Then, the switch assembly 18 is provided while being supported by the bracket 23.

The switch assembly 18 has a box-like outer shape having the same shape as the switch mounting hole 23c, and is cut and raised from the outer surface of the outer shape to provide a locking projection 25.
An engaging collar 26 is provided on the outer periphery of the end where the switch button 19 is located. Then, the switch assembly 18 is fitted into the switch mounting hole 23c from the direction of the arrow in FIG. 2, and the hole edge 23d of the switch mounting hole 23c is engaged with the engaging projection 26 and the engaging collar 2.
It is attached to the bracket 23 by sandwiching with 6.

Then, the front end portion 23b is directed to the front side of the device body 10 and the base end portion 23a is appropriately fixed to a predetermined position of the internal device (not shown). Then, the outer cover 13 is put on the internal equipment. Then, as shown in FIG. 1, the switch button 19 of the switch assembly 18 is exposed from the switch hole 12 a of the side surface exterior cover 12.

Further, as shown in FIG. 1, in the front exterior cover 11 of the exterior cover 13, the upper cover portion 1 thereof is provided.
A rib 30 is provided integrally with 1a. Upper cover part 11a
3, the rib 30 is formed in an inverted L-shape in vertical section, and the rib 30 is projected inward from the inner surface thereof. The rib 30 is
As shown in FIG. 1, the flat plate portion 30a is formed into a substantially right-angled triangular shape in a plane, and a bent portion 30b is raised from one side of the flat plate portion 30a in a right-angled upward direction. And rib 30
A tip portion of the above is extended above the switch assembly 18, and a bent portion 30b is arranged adjacent to the inside of the bracket 23.

When the switch button 19 is operated, the ribs 30 prevent the bracket 23 from being pushed inward by the operation force and bending.

In the illustrated embodiment, the rib 30 is provided integrally with the front exterior cover 11 and is provided inside the exterior cover 13. However, although not shown, the rib 30 may be provided separately from the front exterior cover 11 and may be provided inside the exterior cover 13, or may be integrated with or separate from the inner cover that is inside the exterior cover 13 and covers the internal equipment. It may be provided by the body.

[0017]

Therefore, according to the present invention, the bending of the bracket when the switch button is operated is prevented by the ribs, so that the operation feeling of the switch button can be improved and the switch hole of the exterior cover can be provided. There is no gap between the brackets, which improves the appearance,
It is possible to prevent the possibility of foreign matter entering inside.
