In order to achieve the above object, the present invention provides an LE for an operation unit case having a seat mounting surface for mounting a symbol sheet having a translucent portion for indicating symbols and messages.
In a structure of a display unit in which a board on which D is mounted is assembled and an enclosure for shielding light leakage from the LED is provided in the operation unit case, a long hole is formed through the seat mounting surface and the long length is formed. The surrounding frame is projected along the edge of the hole, a low portion is provided along the edge at the edge of the slot, and the slot is provided in the slot in a direction orthogonal to the longitudinal direction of the slot. Abbreviation T
By partitioning the enclosure of the elongated hole in the longitudinal direction by inserting and inserting a letter-shaped partition plate, the T-shaped partition plate has a stopper portion that sits at the low place at the upper end,
A shielding plate for partitioning the elongated hole is provided below the stopper portion.

The present invention will be described in detail below with reference to the accompanying drawings. FIGS. 1 (a), (b), (c), (d) and (e) are a plan view of an operation part case of one embodiment of the present invention, a perspective view of a partition plate, a perspective view showing an assembled state of both, and an assembled state. 3 is a plan view and a cross-sectional view showing an assembled state. A seat mounting surface 11 (recess) is provided on an operation unit case 10 that constitutes an operation board of the image forming apparatus, and a predetermined number of rectangular elongated holes 12 are formed through the sheet mounting surface 11 to form each elongated hole 12. A plurality of rectangular notches 13 that are orthogonal to the elongated holes are formed in the opposing longitudinal edges 12a at predetermined intervals. The notches 13 formed along the edges 12a are arranged so as to face each other. Each notch 13 is a through hole that communicates with the elongated hole 12 except for a back side portion 13a shown by hatching, and the back side portion 13a is a seat mounting surface 11
It is a supporting surface (low place) slightly lower than the upper surface of.
As shown in (c), a surrounding frame 10a projects downward from the peripheral portions of the elongated hole 12 and the notch 13.

The partition plate 14 shown in (b) is a T plate as shown in the figure.
The stopper 14a is a rectangular thin plate and is integrally formed with a shield plate 14b having a width w2 that is approximately equal to the distance w1 between the support surfaces 13a at the back of the notch 13,
For the dimensions of each part of the partition plate 14, see (c)
As described above, the lower surface of the end edge of the stopper 14a is seated on the support surface 13a when it is inserted into the elongated hole 12 so that it cannot be removed and is supported so as not to be displaced. Further, the thickness of the stopper 14a is made smaller than the distance between the support surface 13a and the upper surface of the seat mounting surface 11 so that the stopper 14a does not project upward from the upper surface of the seat mounting surface 11.

(D) is a plan view showing a state where the partition plate 14 is attached to the seat mounting surface 11, (e) is a cross-sectional view taken along the line AA, in which the LED 2 on the substrate 5 is located between the partition plates 14. The board 5 is assembled and fixed to the operation unit case 10 so as to be inserted in the space, and is further assembled by mounting the symbol sheet 1 on the sheet mounting surface 11 (including fixing of the partition plate 14).
Is complete. If there is a problem in the arrangement of the existing partition plate 14 due to the change of the symbol sheet 1, the addition of LEDs, or the change of the layout (board change), it is possible to deal with it by removing the partition plate 14 from the slot 12. . Further, when a specific display portion on the symbol sheet 1 is difficult to see due to insufficient illumination light amount, an LED for illuminating the display portion can be added by moving the partition plate.

Next, FIGS. 2 (a) to 2 (c) are configuration explanatory views of a second embodiment of the present invention, (a) is a plan view and a BB sectional view of the operating portion case 10, and (b) is a sectional view. ) Is a perspective view and a bottom view of the partition plate, and (c) is a plan view showing an assembled state. A seat mounting surface 21 (recess) is provided on the operation unit case 10, and a predetermined number of rectangular elongated holes 22 are formed in the seat mounting surface 21. A supporting surface 22a, which is a low place indicated by hatching, is provided at the peripheral portion of each elongated hole 22 to form a through hole communicating with the elongated hole 22, and the elongated hole portion excluding the supporting surface 22a penetrates. ing. An enclosing frame 22b is provided so as to project downward from the peripheral portion of the elongated hole 22.

The partition plate 24 shown in (b) is a T plate as shown in the figure.
The stopper 24a, which is a V-shaped, rectangular thin plate, and the shield plate 24b, which has a width w4 approximately equal to the width w3 of the slot 22.
The four corners of the shielding plate 24b are chamfered in an R shape. When the partition plate 24 is mounted in the slot 22, the shield plate 24b is inserted into the slot 22 so that the shield plate 24b obliquely intersects the longitudinal direction of the slot 22, and then the partition plate 214 is twisted. Shield plate 2
By setting 4b in a posture orthogonal to the elongated hole 22, as shown in FIG.
Attach as shown in (c). The R at the corner of the shield plate 24b facilitates the above twisting operation. As a result, the stopper 2
Both ends of 4a can be seated on the support surface 22a of the slot 22.

In this embodiment, the partition plate 24 can be inserted at any position and can be slidably moved in the longitudinal direction of the slot, so that the partition plate can be installed at a high degree of freedom and the LED can be mounted. It becomes easy to add more and move the partition board. Moreover, since the interval between the LEDs can be narrowed,
It is effective for displaying messages. Further, since the elongated hole 22 has a simple shape, it is easy to process.
