Title: Automatic and continuous loading device of cartridge tape
Inventor: HAMADA NOBUYUKI
IPC: G11B15/68
Filed: 1983-02-19
Abstract: PURPOSE:To load a tape into a tape deck in an automatic and continuous way by constituting the titled device of, a store section for 8-track cartridge tape, tape deck for sound record/reproduction, and a tape carrier which extracts the tape out of the store section and carries and loads/unloads the tape to and from the tape deck. CONSTITUTION:A shelf 2 containing plural stages is set in parallel to the moving surface 2 of a tape carrier 1 which slides on an X-Y axis. Then three round bars 3 made of synthetic resin are pierced in a row through vertically each stage 2 to form a tape store section 4. A tape deck containing a tape holding mechanism is set so that the tape insertion slit is positioned at the aperture parts of two tape store sections 9 and 10. A roller 8 containing a lever is coupled to a solenoid 5 moves upward only when the solenoid 5 is energized and holds a magnetic tape. Thus a close contact is secured between the magnetic side of the tape and a reproducing magnetic head. Then the roller 8 drops naturally by its empty weight when the conduction is cut off to the solenoid 5. The roller 8 can be controlled so as not to prevent the in-coming/out-going of the tape when the tape is loaded and unloaded.

Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To prevent jamming even if print operation is started with a linearless label stuck on the outer circumferential surface of a platen roller. SOLUTION: A leaf spring (member preventing a label from being caught) 21 for preventing the part of a linerless label 9 which has passed through a printing section 1 from being caught along the outer circumferential surface of a platen roller 3 is disposed on the downstream side in the label carrying direction at the printing section 1 with the forward end of the leaf spring being located close to the outer circumferential surface of the platen roller 3. Even if the linerless label 9 sticks to the platen roller 3, the sticking part is stripped by means of the leaf spring 21 when the platen roller 3 is turned. Consequently, the linerless label 9 can be prevented from being caught by the platen roller 3 to cause jamming.
