, 16b are provided with projecting protrusions 21 to engage with the square holes 15a, 15b, respectively. In FIG. 5, by pressing the front panel 3 against the 7-palm base 2, the tongue portion 1 is
6X], 161) are engaged with the convex portion 21 of the chassis base 2, and the front panel 3 is locked to the chassis base 2. And the front panel 3 has holes 17a, 17
It is fixed to the guide plate 1 with screws 18a and 18b via the screws 18a and 18b.

Problems to be Solved by the Invention However, the conventional front panel fixing device described above requires screw tightening work to fix the front panel, and if the front panel and the guide plate or chassis base are made of different materials, temperature fluctuations may occur. Dimensional changes occur due to each change.Since the front panel and the front panel are screwed together, the dimensional changes are
This had the disadvantage that the floppy disk would become distorted depending on the location, and if the problem worsened, the floppy disk would not fit smoothly into the floppy disk insertion slot.

The present invention was made in view of these conventional drawbacks.
It is an object of the present invention to provide a front panel fixing device that allows the front panel to be attached to and detached from a guide plate and a chassis base without using screws.

Means for Solving the Problems In order to achieve the above object, the present invention provides a tongue portion having a hole on the back surface of the lower end of the front panel so as to engage with the locking rib of the chassis base, and A claw is provided on the back surface of the upper center of the longitudinal width of the floppy disk slot.
This claw part is designed to lock into a square hole drilled in the front face of the guide plate, and there is also a receiving part on the top end of the front panel into which the front end of the top cover is fitted and abuts, and a receiving part on the top end of the front panel. Appropriate ribs are provided on the back surface, and the ribs come into contact with the guide plate and the chassis base to position and fix the front panel.

Therefore, according to the present invention, the front panel can be easily fixed to the guide plate and the chassis base without fixing with screws, and by fitting the top cover into the front panel and bringing them into contact, the front panel and the guide plate can be connected. The front panel can be attached to and detached from the guide plate and the chassis base without using screws.

Embodiment FIG. 1 is an exploded perspective view showing the configuration of an embodiment of the present invention, FIG. 2 is a back view of the front panel according to this embodiment, and FIGS. 3 and 4 are sectional views of essential parts of the embodiment. be.

In Figure 1, 1 is a guide plate, and chassis base 2
Fixed. Reference numeral 3 designates a front panel, which includes a pair of tongue pieces 5a and 5b having square holes 4a and lb on the back surface of the lower end, a claw portion 7 on the back surface at the upper center of the longitudinal width of the floppy disk insertion slot 6, and a claw portion 7 on the back surface at various places on the back surface. Ribs 8.9.10a, 10b are arranged.

Reference numeral 11 denotes a receiving portion having a recess formed at the upper end of the front panel 3, into which the cover 12 is fitted and abuts. Reference numeral 13 denotes a locking rib provided on the chassis base 2, which engages with the square hole 4 of the tongue portion 5. The length of the locking rib 13 is slightly shorter than the length of the square hole 4, so that the front panel 3 can be held in place even if the front panel 3 undergoes some dimensional change in the longitudinal direction.

Reference numeral 14 denotes a square hole bored in the front surface of the guide plate 1, into which the claw portion 7 of the front panel is fitted and locked.

In the above embodiment, when the front panel 3 is pressed against the guide plate 1 and the shear 7 base 2 in the direction of the arrow shown in FIG. 1, the tongue portion 5.
5 and the claw portion 7 are bent by making the front panel 3 from a flexible material, and are respectively locked in the locking rib 13 and the square hole 14 in the state shown in FIG. 3 or 4. The front panel 3 is positioned in the longitudinal direction by fitting the claw portion 7 into the square hole 14. The ribs 8, 9, and 10 are still in contact with the guide plate 1 and the pace 2, respectively, and the front panel 3 is positioned in the vertical and longitudinal directions. When the cover 12 is further attached, the tip of the cover 12 is fitted into and abuts the upper end recess 11 of the front panel 3.

This embodiment has the advantage that the front panel can be easily fixed to the guide plate and chassis base without fixing the front panel with screws. Furthermore, the front panel can be positioned in the longitudinal direction by fitting the claws on the front panel and the square holes drilled in the guide plate, and the holes provided in the tongue section of the front panel and the locking holes provided in the chassis base make it possible to position the front panel in the longitudinal direction. Since there is an appropriate gap between the front panel and the ribs, there is an advantage that even if the longitudinal dimension of the component changes due to a change in temperature, the front panel will not undergo deformation that would impede its functionality. Furthermore, since the cover is fitted into the front panel to prevent the front panel from bending, the engagement between the claws on the first panel and the guide plate can be maintained.

and a claw portion is provided on the back surface of the approximately central longitudinal width of the floppy disk insertion opening on the front panel, and this claw portion is configured to lock into a square hole drilled in the front surface of the guide plate, A receiving part is provided at the upper end of the front panel where the front end of the top cover is fitted and comes into contact, and appropriate ribs are provided on the back surface of the front panel, and these ribs contact the guide plate and the chassis base to position and fix the front panel. Because of this structure, the front panel can be easily fixed to the guide plate and chassis base without screwing it in place, and by fitting the top cover into the front panel and bringing it into contact, the front panel and guide plate can be easily fixed. This allows the front panel to be maintained in the locked state, and has the effect of allowing the front panel to be attached to and detached from the guide plate and the ear 7 base without using screws.
