JPH02106383A - Method of holding ribbon cartridge with rib - Google Patents

Abstract

PURPOSE:To prevent upper and lower cases from damaging at the time of filling of an ink ribbon and to eliminate the adjustment even if the length of a ribbon cartridge with a rib is altered by providing a fluctuation between a rib attached to the cartridge and a groove cut on a holding plate. CONSTITUTION:While a knob 9 is raising, an arm 8 is rotated in a direction A to move a resin retaining member to a position for retaining a ribbon cartridge 13 with a rib. When the knob 9 is released from a hand, the member retains the cartridge 13 by the spring force of a spring member. Then, a driving motor is driven to fill and ink ribbon in the cartridge 13. In this case, the central deviation of a ribbon feeding roller 3 and a driving shaft 11 is absorbed by the fluctuation between a rib 4 and a groove 10. After the ribbon is completely filled, the knob 9 is raised to rotate the arm 8, and the cartridge 13 is removed. Even if the length of the cartridge 13 is varied, adjustments such as alteration of positioning, alteration of the holding plate are not required.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a method for holding a ribbed ribbon cartridge when filling the ribbed ribbon cartridge with an ink ribbon.

[Conventional technology]

A conventional holding method for filling an ink ribbon into a ribbed ribbon cartridge is disclosed in US Patent No. 4.609.
As shown in No. 422, the ribbon cartridge holding plate has a screw hole in the matrix, which prevents horizontal rotation when moving the elastic member to an appropriate position and filling the ink ribbon into the ribbon cartridge using the drive motor. It is said that Further, a cylinder fixed to a horizontally rotatable arm mounted on the ribbon holding plate held the ribbon cartridge in the vertical direction.

[Problems to be Solved by the Invention] Depending on the length of the ribbon cartridge filled with the ink ribbon, it is necessary to move the drive motor and the rotation-stopping elastic member to the required positions, and by adjusting the positions of the drive motor and the elastic member, However, there was a problem in that the drive shaft and the ribbon feed roller were misaligned, which caused damage to the ribbon cartridge.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method that eliminates the drawbacks of the prior art, eliminates the need for adjustment when the length of a ribbed ribbon cartridge changes, and prevents defects during ink ribbon filling due to improper adjustment.

[Means for Solving the Problems] In the ribbed ribbon cartridge holding method according to the present invention, a groove wider than the rib width of the ribbon cartridge is cut in the ribbon cartridge holding plate, and the backlash between the groove and the rib is prevented when filling the ink ribbon. The groove absorbs misalignment between the ribbon feed roller and the drive shaft in the ribbed ribbon cartridge, and the groove restricts horizontal rotation of the ribbed ribbon cartridge, and an arm rotatable horizontally is provided on the base plate. The present invention is characterized in that the arm has a member movable in the vertical direction, and the ribbed ribbon cartridge is held down by this member.

[Function 1] According to the above structure of the present invention, the misalignment of the drive shaft and the ribbon feed roller when filling the ink ribbon into the ribbon cartridge with a lip is absorbed by the grooves cut in the ribbon cartridge holding plate and the play between the ribs. This prevents defects when filling the ink ribbon, and eliminates the need for adjustment even if the length of the ribbon cartridge changes.

[Example] An example of the present invention will be described based on the drawings using an example of a ribbon winding device.

FIG. 1 is a sectional view of a ribbed ribbon cartridge. FIG. 2 is a plan view of the device, and FIG. 3 is a sectional view.

In the figure, reference numeral 3 denotes a ribbon feed row, and by driving this row, it is possible to fill the ribbon cartridge with an ink droplet. Reference numeral 8 denotes an arm rotatable about a fulcrum shaft 12, and a knob 9 having a spring member 16 at its tip and movable up and down, to which a resin pressing member 17 is fixed. Further, a drive shaft 11 that is inserted into and drives the ribbon feed roller 3 protrudes from a hole made in the holding plate 5. Note that a groove 10 having a width slightly wider than the width of the rib into which the rib 4 of the ribbon cartridge with lip is inserted is cut in the holding plate 5, and a play is provided between the rib 4 and the groove lO.

To explain the operation below, in FIG. 2, the knob 9 rotates the arm 8 to a position where it is removed from the holding plate. Next, the drive shaft 11 is inserted into the ribbon feed roller 3, and the ribbon cartridge is moved so that the rib 4 enters the groove 1O. 13 on the holding plate. And in Fig. 3, knob 9
While lifting it in direction B, rotate the arm 8 in six directions as shown in Fig. 2, move it to a position where the resin holding member 17 can hold the lip-attached ribbon cartridge 13, and release the knob 9 from your hand. The holding member 17 holds down the ribbon cartridge 13 with a lip by the spring force of the spring member 6. Then, the drive motor 15 is driven to fill the ink ribbon into the ribbon cartridge. At this time ribs 4 and 1
The misalignment between the ribbon feed roller 3 and the drive shaft 11 is absorbed by the play of JIIO. After filling, lift the knob 9 and rotate the arm 8 to remove the ribbon cartridge 1.
One stroke of operation ends when 3 is removed and 0 or more is reached.

Further, according to this method, even if the length of the ribbed ribbon cartridge is changed, there is no need to make adjustments such as changing the positioning or changing the holding plate.

[Effect of the invention 1] As explained above, according to the present invention, misalignment between the drive shaft and the ribbon feed roller can be prevented by providing play between the ribs attached to the ribbed ribbon cartridge and the grooves cut in the holding plate. This has the effect of preventing damage to the upper and lower cases that occurs when filling the ink ribbon into the ribbon cartridge. Another advantage is that there is no need to adjust the length of the ribbon cartridge by changing it.

Claims (1)

[Claims] A groove wider than the rib width of the ribbon cartridge is cut into the ribbon cartridge holding plate, and when the ink ribbon is filled, the play between the groove and the rib absorbs misalignment between the ribbon feed roller and the drive shaft in the ribbed ribbon cartridge. Furthermore, horizontal rotation of the ribbed ribbon cartridge is restricted by the groove, an arm is provided on the base plate and is rotatable in the horizontal direction, and the arm is provided with a member that is movable in the vertical direction. , a method for holding a ribbed ribbon cartridge characterized by holding the ribbed ribbon cartridge.
