Abstract

PURPOSE:To fix the type case securely with good operability, by providing a groove part in a front holder which is formed so that it is lower than the other holder, combining a pushing plate which is guided by said groove part, thereby using the pushing plate. CONSTITUTION:The height of the front holder 12 of the holders which accommodate the type case 11 is made lower than that of a rear holder 13. The groove part 14 is provided on the upper surface of the front holder 12. The type case 11 is fixed by using the pushing plate 15 which is slidden along said groove port 14 and whose cross section is of an L shape. That is, the type case 11 is accommodated in the holders from the front side. One side of the pushing plate 15 is coupled in the groove part 14 and advanced by a screw 16 which is pierced through the other side of the plate 15 and screwed into the holder 12. The type case 11 is fixed by the plate 15 (a symbol 17 is a coil spring which pushes back the pushing plate 15 to the outside when the screw 16 is untightened.)

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a type book fixing device in a typewriter.

A conventional device of this type will be explained. In FIGS. 1 to 3, reference numeral 1 denotes a type book, which is attached to a holder 2 and used. At this time, the mounting is carried out with the bottom surface 3 of the type book 1 resting on the receiver 4 of the holder 2. The holder 2 usually consists of a holder 5 on the front as seen from the typist, a holder 6.7.8 on the left hand, and a holder 6.7.8 on the rear right hand.

Now, when mounting the type book 1 on the holder 2, the typist inserts the type book 1 into the holder 2 from the direction of the front holder 5, as shown in FIG.

After installation, there is a slight gap between the type book 1 and the holder 2, and in order to eliminate looseness in this gap, the type book 1 and the holder 2 are fixed by some method.

This fixing method has a great deal to do with the ease with which the type book 1 can be attached and detached, and is usually carried out in the manner shown in FIGS. 4 and 5. That is, in the case shown in FIG. 4, the front holder 6 is threaded and the type book is fixed to the holder by tightening the screw 9 by hand. In this case, the tightening of the screw 9 is done from the front as seen from the typist, so the operability is good, but when it comes to attaching and detaching the printed book, the upper part 10 of the holder 6 makes it difficult to operate.

Further, in the case shown in FIGS. 5(a) and 5(b), the upper part of the front holder 6 is cut off with emphasis on ease of attachment and detachment of printed books. However, in this case, there is no space to install the screws from the front as shown in Figure 4, and the screws 9 are provided in the left hand holder 6 to fix the type book 1, so the screws 9 must be operated from the side, resulting in poor operability. bad.

As described above, conventional devices have had problems with operability.

It is an object of the present invention to solve the above problems and provide a type book fixing device with good operability.

This will be explained below along with examples. In FIGS. 6 to 8, reference numeral 11 denotes a type book, and holders 12 and 13 are provided, and the holder 12 located at the front is formed lower than the holder 13 located at the rear. 14 is a groove provided in the holder 12; 16 is a holding plate having an L-shaped cross section, and its minus piece fits into the groove 14. 16 is a screw passing through the holding plate 16 and screwed into the holder 12;
Reference numeral 7 denotes a spring (coil spring) for pushing back the holding plate 16 to the outside when the screw 16 is loosened.

4-1~ In this embodiment, the holder 12 located on the front side is set lower than the holders on the other sides, and the presser plate 16
Since it is located at a lower position than the holder, it is easy to attach and detach the type book 1. In addition, the type book 1 is
is securely fixed.

9 and 10 show other embodiments, in which a stopper 18 for preventing the presser plate 6 from lifting is attached to the holder 1.
2. Note that the top surface of this stopper 18 is located below the top surface of the holder 1-12, and the type book 11
It does not get in the way of putting on and taking off.

This embodiment has the great effect of reliably preventing the floating of the type book 11 and presser plate 16 from occurring when the screws 16 are tightened.

As is clear from the above description, according to the present invention, the type book fixing screw is located on the front side, and the height of the front part of the holder can be lowered, making it easy to attach and detach the type book. Since it can be fixed, it has a great effect on improving operability.
