The slide slots (58) are defined in the front end of the rear cover (50), communicate with the chamber and slidably receive the rear hooks (42) on the slide bracket (40) respectively. The mounting hole is defined longitudinally in the rear cover (50), slidably receives the cylinder (32) and the shaft (31) and has an inner surface. The ribs (51) are formed on and extend radially inward from the inner surface of the mounting hole and each rib (51) has a front end with an inclined surface corresponding to inclined surface on each of the ridges (311) on the shaft (31). The grooves (52) are defined in the inner surface of the mounting hole respectively between adjacent ribs (51) and slidably receive the alignment projections (321) on the cylinder (32) respectively so the cylinder (32) cannot rotate in the mounting hole. The grooves (52) are divided into two sets of alternate grooves (52). Each of the alternate grooves (52) of one set has a block (521) formed in the groove (52). When the alternate grooves (52) with the blocks (521) engage respectively with the ridges (311) on the shaft (31), the blocks (521) press respectively against the ridges (311) to hold the slide bracket (40) and the core assembly (20) at a forward position relative to the front cover (10) to extend the head (24) of the core assembly (20) out of the front cover (10), as shown inFig. 6 . When the alternate grooves (52) without the blocks (S21) engage respectively with the ridges (311), the head retracts backward into the front cover (10). The strip (53) is formed on and extends forward from the front end of the rear cover (50), is mounted slidably in one of the rail recesses (15) in the front cover (10) and has a recoiling tab (54) and a side locking hook (55). The recoiling tab (54) is formed on the strip (53) and has a distal end. The side locking hook (55) is formed on the distal end and hooks in the locking hole (14) on the front cover (10). The clip (57) is formed on the rear cover (50) and may clip on a chest pocket on a shirt. - The rear cap (61) is mounted on the rear end of the rear cover (50).
- The spring (70) is mounted in the chamber in the rear cover (50) between the front inside wall (59) and the rear hooks (42) on the slide bracket (40) and is hooked by the rear hooks (42).
- With reference to
Figs. 5 and 6 , a user pushes convex portion on the core assembly (20) forward and compresses the spring (70) between the rear hooks (42) of the slide bracket (40) and inside wall (59) of the rear cover (50) to extend the head (24) out through the front opening (12) in the front cover (10). The slide bracket (40) is driven by the core assembly (20) to move forward and the ridges (311) on the shaft (31) moves forward out of the alternate grooves (52) without the blocks (521) in the mounting hole. At the same time, the keys on the shaft (31) completely engage respectively with the keyways in the cylinder (32) to cause the shaft (31) to rotate slightly so the ridges (311) are aligned respectively with alternate ribs (51). When the user releases the core assembly (20), the core assembly (20) slightly moves backward due to the restoring force of the spring (70) between the slide bracket (40) and the rear cover (50). At the same time, the inclined surfaces of the ridges (311) on the shaft (31) slide respectively along the inclined surfaces of the ribs (51) in the rear cover (50) to further rotate the shaft (31). Then the ridges (311) on the shaft (31) engage respectively with the alternate grooves (52) with the blocks (521), are blocked respectively by the blocks (521) and are incapable of entirely sliding respectively into the alternate grooves (52). Therefore, the core assembly (20) and the slide bracket (40) cannot move backward and the head (24) is still held outside the front cover (10). When the user pushes the core assembly (20) forward and then releases the core assembly (20) again, the ridges (311) entirely extend respectively into the alternate grooves (52) without the blocks (521) due to the restoring force of the spring (70) between the slide bracket (40) and the rear cover (50). The slide bracket (40) and the core assembly (20) slide backward to retract the head (24) into the front cover (10). Retracting the head (24) in the front cover (10) prevents dust from being attached the correction tape on the head (24). - With reference to
Figs. 7-11 , a second embodiment of the correction tape dispenser (2) in accordance with the present invention further has a press button (60) to push the slide bracket (40) and the core assembly (20) forward. Features in the second and first embodiments with same reference numbers are identical and function in the same manner. - With reference to
Fig. 8 , the abutment board (43) of the slide bracket (40) further has a protrusion (46) formed on and extending backward from the abutment board (43) and mounted in the bias element to prevent the extending-and-retracting mechanism (30) from falling off. The rear end of the rear cover (50) has a rear opening defined through the rear end and communicating with the chamber. The press button (60) is mounted slidably through the rear opening in the chamber, is hooked by the rear hooks (42) on the slide bracket (40) and abuts the rear end (322) of the cylinder (32). When the user presses the rear hooks (42) on the slide bracket (40) to push the slide bracket (40), the spring (70) the between the rear cover (50) and the press button (60) is compressed. The cylinder (32), the shaft (31) and the core assembly (20) are driven by the slide bracket (40) to move forward. The ridges (311) on the shaft (31) move forward out of the alternate grooves (52) with the blocks (521) in the mounting hole. At the same time, the keys on the shaft (31) completely engage respectively with the keyways in the cylinders (32) to cause the shaft (31) to rotate slightly so the ridges (311) are aligned respectively with alternate ribs (51). When the user releases the press button (60), the core assembly (20) slightly moves backward due to the restoring force of the spring (70) between the slide bracket (40) and the rear cover (50). At the same time, the inclined surfaces of the ridges (311) on the shaft (31) slide respectively along the inclined surfaces of the ribs (51) in the rear cover (50) to further rotate the shaft (31). Then the ridges (311) on the shaft (31) engage respectively with the other alternate grooves (52) with the blocks (521), are blocked respectively by the blocks (521) and are incapable of entirely sliding respectively into the alternate grooves (52). Therefore, the core assembly (20) and the slide bracket (40) cannot move backward and the head (24) is still held outside the front cover (10). When the user pushes the core assembly (20) forward and then releases the core assembly (20) again, the ridges (311) entirely extend respectively into the alternate grooves (52) without the blocks (521) due to the restoring force of the spring (70) between the slide bracket (40) and the rear cover (50). The slide bracket (40) and the core assembly (20) slide backward to retract the head (24) into the front cover (10). - With reference to
Fig. 12 , a third embodiment of the correction tape dispenser in accordance with the present invention has the bias element being a recoiling tab (34) mounted to the front end of the shaft (31) and having a front end pressing against the abutment board (43) of the slide bracket (40). The restoring force of the recoiling tab (34) moves the shaft (31) backward. - With reference to
Fig. 11 , a fourth embodiment of the correction tape dispenser in accordance with the present invention has the bias element being a recoiling segment (48) formed on the abutment board (43) and pressing against the front end of the shaft (31). The restoring force of the recoiling segment (48) moves the shaft (31) backward. - A user may easily press the press button (60) or push the convex portion of the core assembly (20) to extend the head (24) out of the front cover (10). When the user presses the press button (60) or pushes the convex portion again, the head (24) retracts into the front cover to prevent dust from accumulating on the correction tape on the head. Therefore, using the correction tape dispenser is convenient and efficient.
